In commit 9adf40249e, we changed the behavior of the AIL thread to
set its own task state to KILLABLE whenever the timeout value is
nonzero. Unfortunately, this missed the fact that xfsaild_push will
return 50ms (aka a longish sleep) when we reach the push target or the
AIL becomes empty, so xfsaild goes to sleep for a long period of time in
uninterruptible D state.
This results in artificially high load averages because KILLABLE
processes are UNINTERRUPTIBLE, which contributes to load average even
though the AIL is asleep waiting for someone to interrupt it. It's not
blocked on IOs or anything, but people scrap ps for processes that look
like they're stuck in D state, so restore the previous threshold.

It turns out that I misunderstood the difference between the attr and
attr2 feature bits. "attr" means that at some point an attr fork was
created somewhere in the filesystem. "attr2" means that inodes have
variable-sized forks, but says nothing about whether or not there
actually /are/ attr forks in the system.
If we have an attr fork, we only need to check that attr is set.

This reverts commit 28ab976911.
Sense data can be in either fixed format or descriptor format.
SAT-6 revision 1, "10.4.6 Control mode page", defines the D_SENSE bit:
"The SATL shall support this bit as defined in SPC-5 with the following
exception: if the D_ SENSE bit is set to zero (i.e., fixed format sense
data), then the SATL should return fixed format sense data for ATA
PASS-THROUGH commands."
The libata SATL has always kept D_SENSE set to zero by default. (It is
however possible to change the value using a MODE SELECT SG_IO command.)
Failed ATA PASS-THROUGH commands correctly respected the D_SENSE bit,
however, successful ATA PASS-THROUGH commands incorrectly returned the
sense data in descriptor format (regardless of the D_SENSE bit).
Commit 28ab976911 ("ata: libata-scsi: Honor the D_SENSE bit for
CK_COND=1 and no error") fixed this bug for successful ATA PASS-THROUGH
commands.
However, after commit 28ab976911 ("ata: libata-scsi: Honor the D_SENSE
bit for CK_COND=1 and no error"), there were bug reports that hdparm,
hddtemp, and udisks were no longer working as expected.
These applications incorrectly assume the returned sense data is in
descriptor format, without even looking at the RESPONSE CODE field in the
returned sense data (to see which format the returned sense data is in).
Considering that there will be broken versions of these applications around
roughly forever, we are stuck with being bug compatible with older kernels.

But these are part of the ABI between the kernel and firmware on ISP2400
and this part of the TPG support removal changes broke ISP2400 support.
ISP2401 support was not affected because on ISP2401 only a part of
struct sh_css_sp_config is used.

This adds another disk accounting counter to track usage per inode
number (any snapshot ID).
This will be used for a couple things:
- It'll give us a way to tell the user how much space a given file ista
consuming in all snapshots; i.e. how much extra space it's consuming
due to snapshot versioning.
- It counts number of extents and total size of extents (both in btree
keyspace sectors and actual disk usage), meaning it gives us average
extent size: that is, it'll let us cheaply find fragmented files that
should be defragmented.

bkey_fsck_err() was added as an interface that looks like fsck_err(),
but previously all it did was ensure that the appropriate error counter
was incremented in the superblock.
This is a cleanup and bugfix patch that converts it to a wrapper around
fsck_err(). This is needed to fix an issue with the upgrade path to
disk_accounting_v3, where the "silent fix" error list now includes
bkey_fsck errors; fsck_err() handles this in a unified way, and since we
need to change printing of bkey fsck errors from the caller to the inner
bkey_fsck_err() calls, this ends up being a pretty big change.
Als,, rename .invalid() methods to .validate(), for clarity, while we're
changing the function signature anyways (to drop the printbuf argument).

bch2_btree_path_traverse_cached() was previously checking if it could

However, it was using btree_node_relock(), not btree_path_relock();
btree_path_relock() only succeeds if the path was in state
BTREE_ITER_NEED_RELOCK.
If the path was in state BTREE_ITER_NEED_TRAVERSE a full traversal is
needed; this led to a null ptr deref in

When opening a file for exec via do_filp_open(), permission checking is
done against the file's metadata at that moment, and on success, a file
pointer is passed back. Much later in the execve() code path, the file
metadata (specifically mode, uid, and gid) is used to determine if/how
to set the uid and gid. However, those values may have changed since the
permissions check, meaning the execution may gain unintended privileges.
For example, if a file could change permissions from executable and not
set-id:
---------x 1 root root 16048 Aug 7 13:16 target
to set-id and non-executable:
---S------ 1 root root 16048 Aug 7 13:16 target
it is possible to gain root privileges when execution should have been
disallowed.
While this race condition is rare in real-world scenarios, it has been
observed (and proven exploitable) when package managers are updating
the setuid bits of installed programs. Such files start with being
world-executable but then are adjusted to be group-exec with a set-uid
bit. For example, "chmod o-x,u+s target" makes "target" executable only
by uid "root" and gid "cdrom", while also becoming setuid-root:
-rwxr-xr-x 1 root cdrom 16048 Aug 7 13:16 target
becomes:
-rwsr-xr-- 1 root cdrom 16048 Aug 7 13:16 target
But racing the chmod means users without group "cdrom" membership can
get the permission to execute "target" just before the chmod, and when
the chmod finishes, the exec reaches brpm_fill_uid(), and performs the
setuid to root, violating the expressed authorization of "only cdrom
group members can setuid to root".
Re-check that we still have execute permissions in case the metadata
has changed. It would be better to keep a copy from the perm-check time,
but until we can do that refactoring, the least-bad option is to do a
full inode_permission() call (under inode lock). It is understood that
this is safe against dead-locks, but hardly optimal.

The regressing commit is new in 6.10. It assumed that anytime event->prog
is set bpf_overflow_handler() should be invoked to execute the attached bpf
program. This assumption is false for tracing events, and as a result the
regressing commit broke bpftrace by invoking the bpf handler with garbage
inputs on overflow.
Prior to the regression the overflow handlers formed a chain (of length 0,
1, or 2) and perf_event_set_bpf_handler() (the !tracing case) added
bpf_overflow_handler() to that chain, while perf_event_attach_bpf_prog()
(the tracing case) did not. Both set event->prog. The chain of overflow
handlers was replaced by a single overflow handler slot and a fixed call to
bpf_overflow_handler() when appropriate. This modifies the condition there
to check event->prog->type == BPF_PROG_TYPE_PERF_EVENT, restoring the
previous behavior and fixing bpftrace.

[Why]
Tiled display cannot synchronize properly after S3.
The fix for commit 5f0c749158 ("drm/amd/display: Fix for otg
synchronization logic") is not enable in DCN321, which causes
the otg is excluded from synchronization.
[How]
Enable otg synchronization logic in dcn321.

To be able to get to the lowest power state when suspending systems with
DCN3.5+, we must be in IPS before the display hardware is put into
D3cold. So, to ensure that the system always reaches the lowest power
state while suspending, force systems that support IPS to enter idle
optimizations before entering D3cold.

Cc: stable@vger.kernel.org # 6.10+
When hot-unplug a device which has many queues, and guest CPU will has
huge jitter, and unplugging is very slow.
It turns out synchronize_srcu() in irqfd_shutdown() caused the guest
jitter and unplugging latency, so replace synchronize_srcu() with
synchronize_srcu_expedited(), to accelerate the unplugging, and reduce
the guest OS jitter, this accelerates the VM reboot too.
