d01508f2df perf auxtrace: Add mmap_needed to auxtrace_mmap_params 
Add mmap_needed to auxtrace_mmap_params.

Currently an auxtrace mmap is always attempted even if the event is not an
auxtrace event. That works because, when AUX area tracing, there is always
an auxtrace event first for every mmap. Prepare for that not being the
case, which it won't be when sideband tracking events are allowed on
all CPUs even when auxtrace is limited to selected CPUs.

1097b38fb7 perf intel-pt: Add a test for system-wide side band 
Add a test for system-wide side band even when tracing selected CPUs.

The test fails before the patches up to "perf tools: Allow system-wide
events to keep their own CPUs" are applied, passes afterwards.

df76e00383 perf build: Stop using __weak bpf_map_create() to handle older libbpf versions 
By adding a feature test for bpf_map_create() and providing a fallback if
it isn't present in older versions of libbpf.

This also fixes the build with torvalds/master at this point:

  d16495a982 libbpf: remove bpf_create_map*() APIs

As the __weak function fails to build as it calls the now removed
bpf_create_map() API.

08af54b3e5 NFSD: nfsd_file_put() can sleep 
Now that there are no more callers of nfsd_file_put() that might
hold a spin lock, ensure the lockdep infrastructure can catch
newly introduced calls to nfsd_file_put() made while a spinlock
is held.

ce3c4ad7f4 NFSD: Fix possible sleep during nfsd4_release_lockowner() 
nfsd4_release_lockowner() holds clp->cl_lock when it calls
check_for_locks(). However, check_for_locks() calls nfsd_file_get()
/ nfsd_file_put() to access the backing inode's flc_posix list, and
nfsd_file_put() can sleep if the inode was recently removed.

Let's instead rely on the stateowner's reference count to gate
whether the release is permitted. This should be a reliable
indication of locks-in-use since file lock operations and
->lm_get_owner take appropriate references, which are released
appropriately when file locks are removed.

73534617df perf build: Fix btf__load_from_kernel_by_id() feature check 
The btf__load_from_kernel_by_id() only takes one arg, not two.

Committer notes:

I tested it just with an older libbpf, one where
btf__load_from_kernel_by_id() wasn't introduced yet.

A test with a newer dynamic libbpf would fail because the
btf__load_from_kernel_by_id() is there, but takes just one arg.

86c8fb4d22 scsi: storvsc: Removing Pre Win8 related logic 
The latest storvsc code has already removed the support for windows 7 and
earlier. There is still some code logic remaining which is there to support
pre Windows 8 OS. This patch removes these stale logic.
This patch majorly does three things :

1. Removes vmscsi_size_delta and its logic, as the vmscsi_request struct is
same for all the OS post windows 8 there is no need of delta.
2. Simplify sense_buffer_size logic, as there is single buffer size for
all the post windows 8 OS.
3. Embed the vmscsi_win8_extension structure inside the vmscsi_request,
as there is no separate handling required for different OS.

7e4fd16b38 MIPS: RALINK: Define pci_remap_iospace under CONFIG_PCI_DRIVERS_GENERIC 
kernel test robot reports a build error used with clang compiler and
mips-randconfig [1]:

    ld.lld: error: undefined symbol: pci_remap_iospace

we can see the following configs in the mips-randconfig file:

    CONFIG_RALINK=y
    CONFIG_SOC_MT7620=y
    CONFIG_PCI_DRIVERS_LEGACY=y
    CONFIG_PCI=y

CONFIG_RALINK is set, so pci_remap_iospace is defined in the related
arch/mips/include/asm/mach-ralink/spaces.h header file:

    #define pci_remap_iospace pci_remap_iospace

CONFIG_PCI is set, so pci_remap_iospace() in drivers/pci/pci.c is not
built due to pci_remap_iospace is defined under CONFIG_RALINK.

    #ifndef pci_remap_iospace
    int pci_remap_iospace(const struct resource *res, ...)

    $ objdump -d drivers/pci/pci.o | grep pci_remap_iospace
    00004cc8 <devm_pci_remap_iospace>:
        4d18:	10400008 	beqz	v0,4d3c <devm_pci_remap_iospace+0x74>
        4d2c:	1040000c 	beqz	v0,4d60 <devm_pci_remap_iospace+0x98>
        4d70:	1000fff3 	b	4d40 <devm_pci_remap_iospace+0x78>

In addition, CONFIG_PCI_DRIVERS_GENERIC is not set, so pci_remap_iospace()
in arch/mips/pci/pci-generic.c is not built too.

    #ifdef pci_remap_iospace
    int pci_remap_iospace(const struct resource *res, ...)

For the above reasons, undefined reference pci_remap_iospace() looks like
reasonable.

Here are simple steps to reproduce used with gcc and defconfig:

    cd mips.git
    make vocore2_defconfig # set RALINK, SOC_MT7620, PCI_DRIVERS_LEGACY
    make menuconfig        # set PCI
    make

there exists the following build error:

      LD      vmlinux.o
      MODPOST vmlinux.symvers
      MODINFO modules.builtin.modinfo
      GEN     modules.builtin
      LD      .tmp_vmlinux.kallsyms1
    drivers/pci/pci.o: In function `devm_pci_remap_iospace':
    pci.c:(.text+0x4d24): undefined reference to `pci_remap_iospace'
    Makefile:1158: recipe for target 'vmlinux' failed
    make: *** [vmlinux] Error 1

Define pci_remap_iospace under CONFIG_PCI_DRIVERS_GENERIC can fix the build
error, with this patch, no build error remains. This patch is similar with
commit e538e86498 ("MIPS: asm: pci: define arch-specific
'pci_remap_iospace()' dependent on 'CONFIG_PCI_DRIVERS_GENERIC'").

babf0bb978 xfs: Changes for 5.19-rc1 
This update includes:
 - support for printk message indexing.
 - large extent counts to provide support for up to 2^47 data extents and 2^32
   attribute extents, allowing us to scale beyond 4 billion data extents
   to billions of xattrs per inode.
 - conversion of various flags fields to be consistently declared as
   unsigned bit fields.
 - improvements to realtime extent accounting and converts them to per-cpu
   counters to match all the other block and inode accounting.
 - reworks core log formatting code to reduce iterations, have a shorter, cleaner
   fast path and generally be easier to understand and maintain.
 - improvements to rmap btree searches that reduce overhead by up
   to 30% resulting in xfs_scrub runtime reductions of 15%.
 - improvements to reflink that remove the size limitations in remapping operations
   and greatly reduce the size of transaction reservations.
 - reworks the minimum log size calculations to allow us to change transaction
   reservations without changing the minimum supported log size.
 - removal of quota warning support as it has never been used on Linux.
 - intent whiteouts to allow us to cancel intents that are completed entirely
   in memory rather than having use CPU and disk bandwidth formatting and writing
   them into the journal when it is not necessary. This makes rmap, reflink and
   extent freeing slightly more efficient, but provides massive improvements
   for....
 - Logged Attribute Replay feature support. This is a fundamental change to the
   way we modify attributes, laying the foundation for future integration of
   attribute modifications as part of other atomic transactional operations the
   filesystem performs.
 - Lots of cleanups and fixes for the logged attribute replay functionality.

Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Dave Chinner:
 "This is a big update with lots of new code. The summary below them
  all, so I'll just touch on teh higlights. The two main new features
  are Large Extent Counts and Logged Attribute Replay - these are two
  new foundational features that we are building more complex future
  features on top of.

  For upcoming functionality, we need to be able to store hundreds of
  millions of xattrs per inode. The Large Extent Count feature removes
  the limits that prevent this scale of xattr storage, and while we were
  modifying the on disk extent count format we also increased the number
  of data extents we support per inode from 2^32 to 2^47.

  We also need to be able to modify xattrs as part of larger atomic
  transactions rather than as standalone transactions. The Logged
  Attribute Replay feature introduces the infrastructure that allows us
  to use intents to record the attribute modifications in the journal
  before we start them, hence allowing other atomic transactions to log
  attribute modification intents and then defer the actual modification
  to later. If we then crash, log recovery then guarantees that the
  attribute is replayed in the context of the atomic transaction that
  logged the intent.

  A significant chunk of the commits in this merge are for the base
  attribute replay functionality along with fixes, improvements and
  cleanups related to this new functioanlity. Allison deserves a big
  round of thanks for her ongoing work to get this functionality into
  XFS.

  There are also many other smaller changes and improvements, so overall
  this is one of the bigger XFS merge requests in some time.

  I will be following up next week with another smaller pull request -
  we already have another round of fixes and improvements to the logged
  attribute replay functionality just about ready to go. They'll soak
  and test over the next week, and I'll send a pull request for them
  near the end of the merge window.

  Summary:

   - support for printk message indexing.

   - large extent counts to provide support for up to 2^47 data extents
     and 2^32 attribute extents, allowing us to scale beyond 4 billion
     data extents to billions of xattrs per inode.

   - conversion of various flags fields to be consistently declared as
     unsigned bit fields.

   - improvements to realtime extent accounting and converts them to
     per-cpu counters to match all the other block and inode accounting.

   - reworks core log formatting code to reduce iterations, have a

     and maintain.

   - improvements to rmap btree searches that reduce overhead by up to
     30% resulting in xfs_scrub runtime reductions of 15%.

   - improvements to reflink that remove the size limitations in
     remapping operations and greatly reduce the size of transaction
     reservations.

   - reworks the minimum log size calculations to allow us to change
     transaction reservations without changing the minimum supported log
     size.

   - removal of quota warning support as it has never been used on

d7227785e3 sound updates for 5.19-rc1 
Not much dramatic changes at this time, but we've received quite
 a lot of changes for ASoC, while there are still a few fixes and
 quirks for usual HD- and USB-auido.  Here are some highlights.
 
 * ASoC:
 - Overhaul of endianness specification for data formats, avoiding
   needless restrictions due to CODECs
 - Initial stages of Intel AVS driver merge
 - Introduction of v4 IPC mechanism for SOF
 - TDM mode support for AK4613
 - Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
   MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
   nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
 
 * Others
 - A few regression fixes after the USB-audio endpoint management
   refactoring
 - More enhancements for Cirrus HD-audio codec support (still ongoing)
 - Addition of generic serial MIDI driver

RISC-V: Split out the XIP fixups into their own file 
This was broken by the original refactoring (as the XIP definitions
depend on <asm/pgtable.h>) and then more broken by the merge (as I
accidentally took the old version).  This fixes both breakages, while
also pulling this out of <asm/asm.h> to avoid polluting most assembly
files with the XIP fixups.

e908305fb2 Add new functions to alloc check for 5.19-rc1 
Hi Linus,
 
 Please, pull the following patch that adds new alloc functions to alloc
 with multiplies check.
 
 kvmalloc() and kvzalloc() functions have now 2-factor multiplication
 argument forms kvmalloc_array() and kvcalloc().
 
 Add alloc-with-multiplies checks for these new functions.
 
 Thanks

e35c2d8e22 tracing: Reset the function filter after completing trampoline/graph selftest 
The direct trampoline and graph coexistence test sets global_ops to
trace only 'trace_selftest_dynamic_test_func', but does not reset it
after the test is completed, resulting in the function filter being set
already after the system starts. Although it can be reset through the
tracefs interface, it is more or less confusing to the user, and we
should reset it to trace all functions after the trampoline/graph test
completes.

499f12168a tracing: Have event format check not flag %p* on __get_dynamic_array() 
The print fmt check against trace events to make sure that the format does
not use pointers that may be freed from the time of the trace to the time
the event is read, gives a false positive on %pISpc when reading data that
was saved in __get_dynamic_array() when it is perfectly fine to do so, as
the data being read is on the ring buffer.

3159d79b56 kcov: update pos before writing pc in trace function 
In __sanitizer_cov_trace_pc(), previously we write pc before updating pos.
However, some early interrupt code could bypass check_kcov_mode() check
and invoke __sanitizer_cov_trace_pc().  If such interrupt is raised
between writing pc and updating pos, the pc could be overitten by the
recursive __sanitizer_cov_trace_pc().

As suggested by Dmitry, we cold update pos before writing pc to avoid such
interleaving.

Apply the same change to write_comp_data().

863e0d81b6 ocfs2: dlmfs: fix error handling of user_dlm_destroy_lock 
When user_dlm_destroy_lock failed, it didn't clean up the flags it set
before exit.  For USER_LOCK_IN_TEARDOWN, if this function fails because of
lock is still in used, next time when unlink invokes this function, it
will return succeed, and then unlink will remove inode and dentry if lock
is not in used(file closed), but the dlm lock is still linked in dlm lock
resource, then when bast come in, it will trigger a panic due to
user-after-free.  See the following panic call trace.  To fix this,
USER_LOCK_IN_TEARDOWN should be reverted if fail.  And also error should
be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink
fail.

For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN,
USER_LOCK_BUSY is also required to be cleared.  Even though spin lock is
released in between, but USER_LOCK_IN_TEARDOWN is still set, for
USER_LOCK_BUSY, if before every place that waits on this flag,
USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow
waits on the busy flag set by user_dlm_destroy_lock(), then we can
simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails.  Fix
user_dlm_cluster_lock() which is the only function not following this.

0b6d14e3db ocfs2: dlmfs: don't clear USER_LOCK_ATTACHED when destroying lock 
The following function is the only place that checks USER_LOCK_ATTACHED. 
This flag is set when lock request is granted through user_ast() and only
the following function will clear it.

Checking of this flag here is to make sure ocfs2_dlm_unlock is not issued
if this lock is never granted.  For example, lock file is created and then
get removed, open file never happens.

Clearing the flag here is not necessary because this is the only function
that checks it, if another flow is executing user_dlm_destroy_lock(), it
will bail out at the beginning because of USER_LOCK_IN_TEARDOWN and never
check USER_LOCK_ATTACHED.  Drop the clear, so we don't need take care of
it for the following error handling patch.

int user_dlm_destroy_lock(struct user_lock_res *lockres)
{
    ...

    status = 0;
    if (!(lockres->l_flags & USER_LOCK_ATTACHED)) {
        spin_unlock(&lockres->l_lock);
        goto bail;
    }

    lockres->l_flags &= ~USER_LOCK_ATTACHED;
    lockres->l_flags |= USER_LOCK_BUSY;
    spin_unlock(&lockres->l_lock);

	status = ocfs2_dlm_unlock(conn, &lockres->l_lksb, DLM_LKF_VALBLK);
    if (status) {
        user_log_dlm_error("ocfs2_dlm_unlock", status, lockres);
        goto bail;
    }
	...
}

Linus Torvalds
7e062cda7d Networking changes for 5.19. 
Core
 ----
 
  - Support TCPv6 segmentation offload with super-segments larger than
    64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
 
  - Generalize skb freeing deferral to per-cpu lists, instead of
    per-socket lists.
 
  - Add a netdev statistic for packets dropped due to L2 address
    mismatch (rx_otherhost_dropped).
 
  - Continue work annotating skb drop reasons.
 
  - Accept alternative netdev names (ALT_IFNAME) in more netlink
    requests.
 
  - Add VLAN support for AF_PACKET SOCK_RAW GSO.
 
  - Allow receiving skb mark from the socket as a cmsg.
 
  - Enable memcg accounting for veth queues, sysctl tables and IPv6.
 
 BPF
 ---
 
  - Add libbpf support for User Statically-Defined Tracing (USDTs).
 
  - Speed up symbol resolution for kprobes multi-link attachments.
 
  - Support storing typed pointers to referenced and unreferenced
    objects in BPF maps.
 
  - Add support for BPF link iterator.
 
  - Introduce access to remote CPU map elements in BPF per-cpu map.
 
  - Allow middle-of-the-road settings for the
    kernel.unprivileged_bpf_disabled sysctl.
 
  - Implement basic types of dynamic pointers e.g. to allow for
    dynamically sized ringbuf reservations without extra memory copies.
 
 Protocols
 ---------
 
  - Retire port only listening_hash table, add a second bind table
    hashed by port and address. Avoid linear list walk when binding
    to very popular ports (e.g. 443).
 
  - Add bridge FDB bulk flush filtering support allowing user space
    to remove all FDB entries matching a condition.
 
  - Introduce accept_unsolicited_na sysctl for IPv6 to implement
    router-side changes for RFC9131.
 
  - Support for MPTCP path manager in user space.
 
  - Add MPTCP support for fallback to regular TCP for connections
    that have never connected additional subflows or transmitted
    out-of-sequence data (partial support for RFC8684 fallback).
 
  - Avoid races in MPTCP-level window tracking, stabilize and improve
    throughput.
 
  - Support lockless operation of GRE tunnels with seq numbers enabled.
 
  - WiFi support for host based BSS color collision detection.
 
  - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.
 
  - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).
 
  - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).
 
  - Allow matching on the number of VLAN tags via tc-flower.
 
  - Add tracepoint for tcp_set_ca_state().
 
 Driver API
 ----------
 
  - Improve error reporting from classifier and action offload.
 
  - Add support for listing line cards in switches (devlink).
 
  - Add helpers for reporting page pool statistics with ethtool -S.
 
  - Add support for reading clock cycles when using PTP virtual clocks,
    instead of having the driver convert to time before reporting.
    This makes it possible to report time from different vclocks.
 
  - Support configuring low-latency Tx descriptor push via ethtool.
 
  - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.
 
 New hardware / drivers
 ----------------------
 
  - Ethernet:
    - Marvell's Octeon NIC PCI Endpoint support (octeon_ep)
    - Sunplus SP7021 SoC (sp7021_emac)
    - Add support for Renesas RZ/V2M (in ravb)
    - Add support for MediaTek mt7986 switches (in mtk_eth_soc)

Pull networking updates from Jakub Kicinski:
 "Core
  ----

   - Support TCPv6 segmentation offload with super-segments larger than
     64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

   - Generalize skb freeing deferral to per-cpu lists, instead of
     per-socket lists.

   - Add a netdev statistic for packets dropped due to L2 address
     mismatch (rx_otherhost_dropped).

   - Continue work annotating skb drop reasons.

   - Accept alternative netdev names (ALT_IFNAME) in more netlink
     requests.

   - Add VLAN support for AF_PACKET SOCK_RAW GSO.

   - Allow receiving skb mark from the socket as a cmsg.

   - Enable memcg accounting for veth queues, sysctl tables and IPv6.

  BPF
  ---

   - Add libbpf support for User Statically-Defined Tracing (USDTs).

   - Speed up symbol resolution for kprobes multi-link attachments.

   - Support storing typed pointers to referenced and unreferenced
     objects in BPF maps.

   - Add support for BPF link iterator.

   - Introduce access to remote CPU map elements in BPF per-cpu map.

   - Allow middle-of-the-road settings for the
     kernel.unprivileged_bpf_disabled sysctl.

   - Implement basic types of dynamic pointers e.g. to allow for
     dynamically sized ringbuf reservations without extra memory copies.

  Protocols
  ---------

   - Retire port only listening_hash table, add a second bind table
     hashed by port and address. Avoid linear list walk when binding to
     very popular ports (e.g. 443).

   - Add bridge FDB bulk flush filtering support allowing user space to
     remove all FDB entries matching a condition.

   - Introduce accept_unsolicited_na sysctl for IPv6 to implement
     router-side changes for RFC9131.

   - Support for MPTCP path manager in user space.

   - Add MPTCP support for fallback to regular TCP for connections that
     have never connected additional subflows or transmitted
     out-of-sequence data (partial support for RFC8684 fallback).

   - Avoid races in MPTCP-level window tracking, stabilize and improve
     throughput.

   - Support lockless operation of GRE tunnels with seq numbers enabled.

   - WiFi support for host based BSS color collision detection.

   - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

   - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).

   - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).

   - Allow matching on the number of VLAN tags via tc-flower.

   - Add tracepoint for tcp_set_ca_state().

  Driver API
  ----------

   - Improve error reporting from classifier and action offload.

   - Add support for listing line cards in switches (devlink).

   - Add helpers for reporting page pool statistics with ethtool -S.

   - Add support for reading clock cycles when using PTP virtual clocks,
     instead of having the driver convert to time before reporting. This
     makes it possible to report time from different vclocks.

   - Support configuring low-latency Tx descriptor push via ethtool.

   - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

  New hardware / drivers

   - Ethernet:
      - Marvell's Octeon NIC PCI Endpoint support (octeon_ep)

Therefore, add the "settings" file with timeout variable so users can set
the "timeout" value.
