fcc79e1714 Networking changes for 6.13.
The most significant set of changes is the per netns RTNL. The new
 behavior is disabled by default, regression risk should be contained.
 
 Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
 default value from PTP_1588_CLOCK_KVM, as the first is intended to be
 a more reliable replacement for the latter.
 
 Core
 ----
 
  - Started a very large, in-progress, effort to make the RTNL lock
    scope per network-namespace, thus reducing the lock contention
    significantly in the containerized use-case, comprising:
    - RCU-ified some relevant slices of the FIB control path
    - introduce basic per netns locking helpers
    - namespacified the IPv4 address hash table
    - remove rtnl_register{,_module}() in favour of rtnl_register_many()
    - refactor rtnl_{new,del,set}link() moving as much validation as
      possible out of RTNL lock
    - convert all phonet doit() and dumpit() handlers to RCU
    - convert IPv4 addresses manipulation to per-netns RTNL
    - convert virtual interface creation to per-netns RTNL
    the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
    knob, disabled by default ad interim.
 
  - Introduce NAPI suspension, to efficiently switching between busy
    polling (NAPI processing suspended) and normal processing.
 
  - Migrate the IPv4 routing input, output and control path from direct
    ToS usage to DSCP macros. This is a work in progress to make ECN
    handling consistent and reliable.
 
  - Add drop reasons support to the IPv4 rotue input path, allowing
    better introspection in case of packets drop.
 
  - Make FIB seqnum lockless, dropping RTNL protection for read
    access.
 
  - Make inet{,v6} addresses hashing less predicable.
 
  - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
    and timestamps
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Add small file operations for debugfs, to reduce the struct ops size.
 
  - Refactoring and optimization for the implementation of page_frag API,
    This is a preparatory work to consolidate the page_frag
    implementation.
 
 Netfilter
 ---------
 
  - Optimize set element transactions to reduce memory consumption
 
  - Extended netlink error reporting for attribute parser failure.
 
  - Make legacy xtables configs user selectable, giving users
    the option to configure iptables without enabling any other config.
 
  - Address a lot of false-positive RCU issues, pointed by recent
    CI improvements.
 
 BPF
 ---
 
  - Put xsk sockets on a struct diet and add various cleanups. Overall,
    this helps to bump performance by 12% for some workloads.
 
  - Extend BPF selftests to increase coverage of XDP features in
    combination with BPF cpumap.
 
  - Optimize and homogenize bpf_csum_diff helper for all archs and also
    add a batch of new BPF selftests for it.
 
  - Extend netkit with an option to delegate skb->{mark,priority}
    scrubbing to its BPF program.
 
  - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
    programs.
 
 Protocols
 ---------
 
  - Introduces 4-tuple hash for connected udp sockets, speeding-up
    significantly connected sockets lookup.
 
  - Add a fastpath for some TCP timers that usually expires after close,
    the socket lock contention.
 
  - Add inbound and outbound xfrm state caches to speed up state lookups.
 
  - Avoid sending MPTCP advertisements on stale subflows, reducing
    risks on loosing them.
 
  - Make neighbours table flushing more scalable, maintaining per device
    neigh lists.
 
 Driver API
 ----------
 
  - Introduce a unified interface to configure transmission H/W shaping,
    and expose it to user-space via generic-netlink.
 
  - Add support for per-NAPI config via netlink. This makes napi
    configuration persistent across queues removal and re-creation.
    Requires driver updates, currently supported drivers are:
    nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
 
  - Add ethtool support for writing SFP / PHY firmware blocks.
 
  - Track RSS context allocation from ethtool core.
 
  - Implement support for mirroring to DSA CPU port, via TC mirror
    offload.
 
  - Consolidate FDB updates notification, to avoid duplicates on
    device-specific entries.
 
  - Expose DPLL clock quality level to the user-space.
 
  - Support master-slave PHY config via device tree.
 
 Tests and tooling
 -----------------
 
  - forwarding: introduce deferred commands, to simplify
    the cleanup phase

7d75606665 pwm: Changes for v6.13-rc1
This pull request prominently contains a new abstraction for PWM
 waveforms that is more expressive that the legacy one. Compared to the
 old abstraction it contains a duty_offset member instead of polarity.
 This new abstraction is already used in an ADC driver merged into the
 iio tree. So I expect you will get a part of this tree also via the iio
 pull request for 6.13-rc1 (tag pwm/duty_offset-for-6.13-rc1).
 
 Otherwise it's the usual collection of fixes, cleanups and dt doc
 updates.
 
 This time around thanks go to Andy Shevchenko, Clark Wang, Conor Dooley,
 David Lechner, Dimitri Fedrau, Frank Li, Jun Li, Kelvin Zhang, Krzysztof
 Kozlowski, Nuno Sa, Shen Lichuan and Trevor Gamblin for code
 contributions, testing and review.

 "This contains a new abstraction for PWM waveforms that is more
  expressive that the legacy one. Compared to the old abstraction it
  contains a duty_offset member instead of polarity. This new
  abstraction is already used in an ADC driver merged into the iio tree.

  The new API requires changes to the lowlevel drivers. For now there
  are two drivers that are converted to the new API (axi-pwmgen and

  not yet converted only work with the older API.

Pull io_uring updates from Jens Axboe:

 - Cleanups of the eventfd handling code, making it fully private.

 - Support for sending a sync message to another ring, without having a
   ring available to send a normal async message.

 - Get rid of the separate unlocked hash table, unify everything around
   the single locked one.

 - Add support for ring resizing. It can be hard to appropriately size
   the CQ ring upfront, if the application doesn't know how busy it will
   be. This results in applications sizing rings for the most busy case,
   which can be wasteful. With ring resizing, they can start small and
   grow the ring, if needed.

 - Add support for fixed wait regions, rather than needing to copy the
   same wait data tons of times for each wait operation.

 - Rewrite the resource node handling, which before was serialized per
   ring. This caused issues with particularly fixed files, where one
   file waiting on IO could hold up putting and freeing of other
   unrelated files. Now each node is handled separately. New code is
   much simpler too, and was a net 250 line reduction in code.

 - Add support for just doing partial buffer clones, rather than always
   cloning the entire buffer table.

 - Series adding static NAPI support, where a specific NAPI instance is
   used rather than having a list of them available that need lookup.

 - Add support for mapped regions, and also convert the fixed wait
   support mentioned above to that concept. This avoids doing special
   mappings for various planned features, and folds the existing
   registered wait into that too.

 - Add support for hybrid IO polling, which is a variant of strict
   IOPOLL but with an initial sleep delay to avoid spinning too early
   and wasting resources on devices that aren't necessarily in the < 5
   usec category wrt latencies.

 - Various cleanups and little fixes.

Pull btrfs updates from David Sterba:
 "Changes outside of btrfs: add io_uring command flag to track a dying
  task (the rest will go via the block git tree).

  User visible changes:

   - wire encoded read (ioctl) to io_uring commands, this can be used on
     itself, in the future this will allow 'send' to be asynchronous. As
     a consequence, the encoded read ioctl can also work in non-blocking
     mode

   - new ioctl to wait for cleaned subvolumes, no need to use the
     generic and root-only SEARCH_TREE ioctl, will be used by "btrfs
     subvol sync"

   - recognize different paths/symlinks for the same devices and don't
     report them during rescanning, this can be observed with LVM or DM

   - seeding device use case change, the sprout device (the one
     capturing new writes) will not clear the read-only status of the
     super block; this prevents accumulating space from deleted
     snapshots

  Performance improvements:

   - reduce lock contention when traversing extent buffers

   - reduce extent tree lock contention when searching for inline
     backref

   - switch from rb-trees to xarray for delayed ref tracking,
     improvements due to better cache locality, branching factors and
     more compact data structures

   - enable extent map shrinker again (prevent memory exhaustion under
     some types of IO load), reworked to run in a single worker thread
     (there used to be problems causing long stalls under memory
     pressure)

  Core changes:

   - raid-stripe-tree feature updates:
       - make device replace and scrub work
       - implement partial deletion of stripe extents
       - new selftests

   - split the config option BTRFS_DEBUG and add EXPERIMENTAL for
     features that are experimental or with known problems so we don't
     misuse debugging config for that

   - subpage mode updates (sector < page):
       - update compression implementations
       - update writepage, writeback

   - continued folio API conversions:
       - buffered writes

   - make buffered write copy one page at a time, preparatory work for
     future integration with large folios, may cause performance drop

   - proper locking of root item regarding starting send

   - error handling improvements

   - code cleanups and refactoring:
       - dead code removal
       - unused parameter reduction
       - lockdep assertions"

Pull misc vfs updates from Christian Brauner:
 "Features:

   - Fixup and improve NLM and kNFSD file lock callbacks

     Last year both GFS2 and OCFS2 had some work done to make their
     locking more robust when exported over NFS. Unfortunately, part of
     that work caused both NLM (for NFS v3 exports) and kNFSD (for
     NFSv4.1+ exports) to no longer send lock notifications to clients

     This in itself is not a huge problem because most NFS clients will
     still poll the server in order to acquire a conflicted lock

     It's important for NLM and kNFSD that they do not block their
     kernel threads inside filesystem's file_lock implementations
     because that can produce deadlocks. We used to make sure of this by
     only trusting that posix_lock_file() can correctly handle blocking
     lock calls asynchronously, so the lock managers would only setup
     their file_lock requests for async callbacks if the filesystem did
     not define its own lock() file operation

     However, when GFS2 and OCFS2 grew the capability to correctly
     handle blocking lock requests asynchronously, they started
     signalling this behavior with EXPORT_OP_ASYNC_LOCK, and the check
     for also trusting posix_lock_file() was inadvertently dropped, so
     now most filesystems no longer produce lock notifications when
     exported over NFS

     Fix this by using an fop_flag which greatly simplifies the problem
     and grooms the way for future uses by both filesystems and lock
     managers alike

   - Add a sysctl to delete the dentry when a file is removed instead of
     making it a negative dentry

     Commit 681ce86235 ("vfs: Delete the associated dentry when
     deleting a file") introduced an unconditional deletion of the
     associated dentry when a file is removed. However, this led to
     performance regressions in specific benchmarks, such as
     ilebench.sum_operations/s, prompting a revert in commit
     4a4be1ad3a ("Revert "vfs: Delete the associated dentry when
     deleting a file""). This reintroduces the concept conditionally
     through a sysctl

   - Expand the statmount() system call:

       * Report the filesystem subtype in a new fs_subtype field to
         e.g., report fuse filesystem subtypes

       * Report the superblock source in a new sb_source field

       * Add a new way to return filesystem specific mount options in an
         option array that returns filesystem specific mount options
         separated by zero bytes and unescaped. This allows caller's to
         retrieve filesystem specific mount options and immediately pass
         them to e.g., fsconfig() without having to unescape or split
         them

       * Report security (LSM) specific mount options in a separate
         security option array. We don't lump them together with
         filesystem specific mount options as security mount options are
         generic and most users aren't interested in them

         The format is the same as for the filesystem specific mount
         option array

   - Support relative paths in fsconfig()'s FSCONFIG_SET_STRING command

   - Optimize acl_permission_check() to avoid costly {g,u}id ownership
     checks if possible

   - Use smp_mb__after_spinlock() to avoid full smp_mb() in evict()

   - Add synchronous wakeup support for ep_poll_callback.

     Currently, epoll only uses wake_up() to wake up task. But sometimes
     there are epoll users which want to use the synchronous wakeup flag
     to give a hint to the scheduler, e.g., the Android binder driver.
     So add a wake_up_sync() define, and use wake_up_sync() when sync is
     true in ep_poll_callback()

  Fixes:

   - Fix kernel documentation for inode_insert5() and iget5_locked()

   - Annotate racy epoll check on file->f_ep

   - Make F_DUPFD_QUERY associative

   - Avoid filename buffer overrun in initramfs

   - Don't let statmount() return empty strings

   - Add a cond_resched() to dump_user_range() to avoid hogging the CPU

   - Don't query the device logical blocksize multiple times for hfsplus

   - Make filemap_read() check that the offset is positive or zero

  Cleanups:

Merge tag 'vfs-6.13.mgtime' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs multigrain timestamps from Christian Brauner:
 "This is another try at implementing multigrain timestamps. This time
  with significant help from the timekeeping maintainers to reduce the
  performance impact.

  Thomas provided a base branch that contains the required timekeeping
  interfaces for the VFS. It serves as the base for the multi-grain
  timestamp work:

   - Multigrain timestamps allow the kernel to use fine-grained
     timestamps when an inode's attributes is being actively observed
     via ->getattr(). With this support, it's possible for a file to get
     a fine-grained timestamp, and another modified after it to get a
     coarse-grained stamp that is earlier than the fine-grained time. If
     this happens then the files can appear to have been modified in
     reverse order, which breaks VFS ordering guarantees.

     To prevent this, a floor value is maintained for multigrain
     timestamps. Whenever a fine-grained timestamp is handed out, record
     it, and when later coarse-grained stamps are handed out, ensure
     they are not earlier than that value. If the coarse-grained
     timestamp is earlier than the fine-grained floor, return the floor
     value instead.

     The timekeeper changes add a static singleton atomic64_t into
     timekeeper.c that is used to keep track of the latest fine-grained
     time ever handed out. This is tracked as a monotonic ktime_t value
     to ensure that it isn't affected by clock jumps. Because it is
     updated at different times than the rest of the timekeeper object,
     the floor value is managed independently of the timekeeper via a
     cmpxchg() operation, and sits on its own cacheline.

     Two new public timekeeper interfaces are added:

      (1) ktime_get_coarse_real_ts64_mg() fills a timespec64 with the
          later of the coarse-grained clock and the floor time

      (2) ktime_get_real_ts64_mg() gets the fine-grained clock value,
          and tries to swap it into the floor. A timespec64 is filled
          with the result.

   - The VFS has always used coarse-grained timestamps when updating the
     ctime and mtime after a change. This has the benefit of allowing
     filesystems to optimize away a lot metadata updates, down to around
     1 per jiffy, even when a file is under heavy writes.

     Unfortunately, this has always been an issue when we're exporting
     via NFSv3, which relies on timestamps to validate caches. A lot of
     changes can happen in a jiffy, so timestamps aren't sufficient to
     help the client decide when to invalidate the cache. Even with
     NFSv4, a lot of exported filesystems don't properly support a
     change attribute and are subject to the same problems with
     timestamp granularity. Other applications have similar issues with
     timestamps (e.g backup applications).

     If we were to always use fine-grained timestamps, that would
     improve the situation, but that becomes rather expensive, as the
     underlying filesystem would have to log a lot more metadata
     updates.

     This adds a way to only use fine-grained timestamps when they are
     being actively queried. Use the (unused) top bit in
     inode->i_ctime_nsec as a flag that indicates whether the current
     timestamps have been queried via stat() or the like. When it's set,
     we allow the kernel to use a fine-grained timestamp iff it's
     necessary to make the ctime show a different value.

     This solves the problem of being able to distinguish the timestamp
     between updates, but introduces a new problem: it's now possible
     for a file being changed to get a fine-grained timestamp. A file
     that is altered just a bit later can then get a coarse-grained one
     that appears older than the earlier fine-grained time. This
     violates timestamp ordering guarantees.

     This is where the earlier mentioned timkeeping interfaces help. A
     global monotonic atomic64_t value is kept that acts as a timestamp
     floor. When we go to stamp a file, we first get the latter of the
     current floor value and the current coarse-grained time. If the
     inode ctime hasn't been queried then we just attempt to stamp it
     with that value.

     If it has been queried, then first see whether the current coarse
     time is later than the existing ctime. If it is, then we accept
     that value. If it isn't, then we get a fine-grained time and try to
     swap that into the global floor. Whether that succeeds or fails, we
     take the resulting floor time, convert it to realtime and try to
     swap that into the ctime.

     We take the result of the ctime swap whether it succeeds or fails,
     since either is just as valid.

     Filesystems can opt into this by setting the FS_MGTIME fstype flag.
     Others should be unaffected (other than being subject to the same
     floor value as multigrain filesystems)"

So remove the field and grab the bytenr from either the index key or any
other place where it's available (delayed refs). This reduces the size of
struct btrfs_qgroup_extent_record from 40 bytes down to 32 bytes, meaning
that we now can store 128 instances of this structure instead of 102 per

fc9de52de3 rxrpc: Fix missing locking causing hanging calls

will be prioritised over the connection and it will be removed from
local->new_client_calls by rxrpc_disconnect_client_call() without a lock
being held.  This may cause other calls on the list to disappear if a race
occurs.

MCA_SYND1 and MCA_SYND2.

These registers will include supplemental error information in addition to the
existing MCA_SYND register. The data within these registers is considered
valid if MCA_STATUS[SyndV] is set.

Userspace error decoding tools like rasdaemon gather related hardware error
information through the tracepoints.

Therefore, export these two registers through the mce_record tracepoint so
that tools like rasdaemon can parse them and output the supplemental error
information like FRU text contained in them.

750fd23926 x86/mce: Add wrapper for struct mce to export vendor specific info
Currently, exporting new additional machine check error information
involves adding new fields for the same at the end of the struct mce.
This additional information can then be consumed through mcelog or
tracepoint.

However, as new MSRs are being added (and will be added in the future)
by CPU vendors on their newer CPUs with additional machine check error
information to be exported, the size of struct mce will balloon on some
CPUs, unnecessarily, since those fields are vendor-specific. Moreover,
different CPU vendors may export the additional information in varying
sizes.

The problem particularly intensifies since struct mce is exposed to
userspace as part of UAPI. It's bloating through vendor-specific data
should be avoided to limit the information being sent out to userspace.

Add a new structure mce_hw_err to wrap the existing struct mce. The same
will prevent its ballooning since vendor-specifc data, if any, can now be
exported through a union within the wrapper structure and through
__dynamic_array in mce_record tracepoint.

Furthermore, new internal kernel fields can be added to the wrapper
struct without impacting the user space API.

afs: Fix missing subdir edit when renamed between parent dirs
When rename moves an AFS subdirectory between parent directories, the
subdir also needs a bit of editing: the ".." entry needs updating to point
to the new parent (though I don't make use of the info) and the DV needs
incrementing by 1 to reflect the change of content.  The server also sends
a callback break notification on the subdirectory if we have one, but we
can take care of recovering the promise next time we access the subdir.

This can be triggered by something like:

    mount -t afs %example.com:xfstest.test20 /xfstest.test/
    mkdir /xfstest.test/{aaa,bbb,aaa/ccc}
    touch /xfstest.test/bbb/ccc/d
    mv /xfstest.test/{aaa/ccc,bbb/ccc}
    touch /xfstest.test/bbb/ccc/e

When the pathwalk for the second touch hits "ccc", kafs spots that the DV
is incorrect and downloads it again (so the fix is not critical).

Fix this, if the rename target is a directory and the old and new
parents are different, by:

 (1) Incrementing the DV number of the target locally.

 (2) Editing the ".." entry in the target to refer to its new parent's
     vnode ID and uniquifier.

37f0b47c51 mm: khugepaged: fix the arguments order in khugepaged_collapse_file trace point
The "addr" and "is_shmem" arguments have different order in TP_PROTO and
TP_ARGS.  This resulted in the incorrect trace result:

text-hugepage-644429 [276] 392092.878683: mm_khugepaged_collapse_file:
mm=0xffff20025d52c440, hpage_pfn=0x200678c00, index=512, addr=1, is_shmem=0,
filename=text-hugepage, nr=512, result=failed

The value of "addr" is wrong because it was treated as bool value, the
type of is_shmem.

Fix the order in TP_PROTO to keep "addr" is before "is_shmem" since the
original patch review suggested this order to achieve best packing.

And use "lx" for "addr" instead of "ld" in TP_printk because address is
typically shown in hex.

After the fix, the trace result looks correct:

text-hugepage-7291  [004]   128.627251: mm_khugepaged_collapse_file:
mm=0xffff0001328f9500, hpage_pfn=0x20016ea00, index=512, addr=0x400000,

Merge patch series "timekeeping/fs: multigrain timestamp redux"
Jeff Layton <jlayton@kernel.org> says:

The VFS has always used coarse-grained timestamps when updating the
ctime and mtime after a change. This has the benefit of allowing
filesystems to optimize away a lot metadata updates, down to around 1
per jiffy, even when a file is under heavy writes.

Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide when to invalidate the cache. Even with NFSv4, a lot of
exported filesystems don't properly support a change attribute and are
subject to the same problems with timestamp granularity. Other
applications have similar issues with timestamps (e.g backup
applications).

If we were to always use fine-grained timestamps, that would improve the
situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.

What we need is a way to only use fine-grained timestamps when they are
being actively queried. Use the (unused) top bit in inode->i_ctime_nsec
as a flag that indicates whether the current timestamps have been
queried via stat() or the like. When it's set, we allow the kernel to
use a fine-grained timestamp iff it's necessary to make the ctime show
a different value.

This solves the problem of being able to distinguish the timestamp
between updates, but introduces a new problem: it's now possible for a
file being changed to get a fine-grained timestamp. A file that is
altered just a bit later can then get a coarse-grained one that appears
older than the earlier fine-grained time. This violates timestamp
ordering guarantees.

To remedy this, keep a global monotonic atomic64_t value that acts as a
timestamp floor.  When we go to stamp a file, we first get the latter of
the current floor value and the current coarse-grained time. If the
inode ctime hasn't been queried then we just attempt to stamp it with
that value.

If it has been queried, then first see whether the current coarse time
is later than the existing ctime. If it is, then we accept that value.
If it isn't, then we get a fine-grained time and try to swap that into
the global floor. Whether that succeeds or fails, we take the resulting
floor time, convert it to realtime and try to swap that into the ctime.

We take the result of the ctime swap whether it succeeds or fails, since
either is just as valid.

Filesystems can opt into this by setting the FS_MGTIME fstype flag.
Others should be unaffected (other than being subject to the same floor
value as multigrain filesystems).

netfs: In readahead, put the folio refs as soon extracted
netfslib currently defers dropping the ref on the folios it obtains during
readahead to after it has started I/O on the basis that we can do it whilst
we wait for the I/O to complete, but this runs the risk of the I/O
collection racing with this in future.

Furthermore, Matthew Wilcox strongly suggests that the refs should be
dropped immediately, as readahead_folio() does (netfslib is using
__readahead_batch() which doesn't drop the refs).

bfc4a245a7 dma-mapping: fix DMA API tracing for chained scatterlists
scatterlist allocations can be chained, and thus all iterations need to
use the chain-aware iterators.  Switch the newly added tracing to use the
proper iterators so that they work with chained scatterlists.

In this series, the main changes include 1) converting major IO paths to use
 folio, and 2) adding various knobs to control GC more flexibly for Zoned
 devices. In addition, there are several patches to address corner cases of
 atomic file operations and better support for file pinning on zoned device.
 
 Enhancement:
  - add knobs to tune foreground/background GCs for Zoned devices
  - convert IO paths to use folio
  - reduce expensive checkpoint trigger frequency
  - allow F2FS_IPU_NOCACHE for pinned file
  - forcibly migrate to secure space for zoned device file pinning
  - get rid of buffer_head use
  - add write priority option based on zone UFS
  - get rid of online repair on corrupted directory
 
 Bug fix:
  - fix to don't panic system for no free segment fault injection
  - fix to don't set SB_RDONLY in f2fs_handle_critical_error()
  - avoid unused block when dio write in LFS mode
  - compress: don't redirty sparse cluster during {,de}compress
  - check discard support for conventional zones
  - atomic: prevent atomic file from being dirtied before commit
  - atomic: fix to check atomic_file in f2fs ioctl interfaces
  - atomic: fix to forbid dio in atomic_file
  - atomic: fix to truncate pagecache before on-disk metadata truncation

d7dfb07d4d firewire updates for v6.12
The batch of changes includes the followwing:
 
 - Replacing tasklet with usual workqueue for isochronous context
 - Replacing IDR with XArray
 - Utilizing guard macro where possible
 - Printing deprecation warning when enabling debug parameter of
   firewire-ohci module
 
 Additionally, it includes a single patch for sound subsystem which the
 subsystem maintainer acked:
 
 - Switching to nonatomic PCM operation
 
 In FireWire subsystem, tasklet has been used as the bottom half of 1394
 OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
 been available, and some developers have proposed replacing tasklet with
 BH workqueue. While it is fortunate that developers are still considering
 the legacy subsystem, a simple replacement is not necessarily suitable.
 
 As a first step towards dropping tasklet, I've investigated the
 feasibility for 1394 OHCI isochronous context, and concluded that usual
 workqueue is available. In the context, the batch of packets is processed
 in the specific queue, thus the timing jitter caused by task scheduling is
 not so critical. Additionally, DMA transmission can be scheduled
 per-packet basis, therefore the context can be sleep between the operation
 of transmissions. Furthermore, in-kernel protocol implementation involves
 some CPU-bound tasks, which can sometimes consumes CPU time so long. These
 characteristics suggest that usual workqueue is suitable, through BH
 workqueues are not.
 
 The replacement with usual workqueue allows unit drivers to process the
 content of packets in non-atomic context. It brings some reliefs to some
 drivers in sound subsystem that spin-lock is not mandatory anymore during
 isochronous packet processing.

88264981f2 sched_ext: Initial pull request for v6.12
This is the initial pull request of sched_ext. The v7 patchset
 (https://lkml.kernel.org/r/20240618212056.2833381-1-tj@kernel.org) is
 applied on top of tip/sched/core + bpf/master as of Jun 18th.
 
   tip/sched/core 793a62823d1c ("sched/core: Drop spinlocks on contention iff kernel is preempti
 ble")
   bpf/master f6afdaf72a ("Merge branch 'bpf-support-resilient-split-btf'")
 
 Since then, the following pulls were made:
 
 - v6.11-rc1 is pulled to keep up with the mainline.
 
 - tip/sched/core was pulled several times:
 
   - 7b9f6c864a, 0df340ceae, 5ac998574f, 0b1777f0fa: To resolve
     conflicts. See each commit for details on conflicts and their
     resolutions.
 
   - d7b01aef9d: To receive fd03c5b858 ("sched: Rework pick_next_task()")
     and related commits. @prev in added to sched_class->put_prev_task() and
     put_prev_task() is reordered after ->pick_task(), which makes
     sched_class->switch_class() unnecessary. The follow-up commits update
     sched_ext accordingly and drop sched_class->switch_class().
 
 - bpf/master was pulled to receive baebe9aaba ("bpf: allow passing struct
   bpf_iter_<type> as kfunc arguments") and related changes in preparation
   for the DSQ iterator patchset
 
 To obtain the net sched_ext changes, diff against:
 
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext.git for-6.12-base
 
 which is the merge of:
 
   tip/sched/core bc9057da1a ("sched/cpufreq: Use NSEC_PER_MSEC for deadline task")
   bpf/master 2ad6d23f46 ("selftests/bpf: Do not update vmlinux.h unnecessarily")
 
 Since the v7 patchset, the following changes were made:
 
 - cpuperf support which was a part of the v6 patchset was posted separately
   and then applied after reviews.
 
 - cgroup support which was a part of the v6 patchset was posted seprately,
   iterated and then applied.
 
 - Improve integration with sched core.
 
 - Double locking usage in migration paths dropped. Depend on
   TASK_ON_RQ_MIGRATING synchronization instead.
 
 - The BPF scheduler couldn't directly dispatch to the local DSQ of another
   CPU using a SCX_DSQ_LOCAL_ON verdict. This caused difficulties around
   handling non-wakeup enqueues. Updated so that SCX_DSQ_LOCAL_ON can be used
   in the enqueue path too.
 
 - DSQ iterator which was a part of the v6 patchset was posted separately.
   The iterator itself was applied after a couple revisions. The associated
   selective consumption kfunc can use further improvements and is still
   being worked on.
 
 - scx_bpf_dispatch[_vtime]_from_dsq() added to increase flexibility. A task
   can now be transferred between two DSQs from almost any context. This
   involved significant refactoring of migration code.
 
 - Various fixes and improvements.
 
 As the branch is based on top of tip/sched/core + bpf/master, please merge
 after both are applied.

Pull sched_ext support from Tejun Heo:
 "This implements a new scheduler class called ‘ext_sched_class’, or
  sched_ext, which allows scheduling policies to be implemented as BPF
  programs.

  The goals of this are:

   - Ease of experimentation and exploration: Enabling rapid iteration
     of new scheduling policies.

   - Customization: Building application-specific schedulers which
     implement policies that are not applicable to general-purpose
     schedulers.

   - Rapid scheduler deployments: Non-disruptive swap outs of scheduling
     policies in production environments"
