5641ace544 ext4: add commit tid info in ext4_fc_commit_start/stop trace events 
This adds commit_tid info in ext4_fc_commit_start/stop which is helpful
in debugging fast_commit issues.

For e.g. issues where due to jbd2 journal full commit, FC miss to commit
updates to a file.

Also improves TP_prink format string i.e. all ext4 and jbd2 trace events
starts with "dev MAjOR,MINOR". Let's follow the same convention while we
are still at it.

d9bf099cb9 ext4: add commit_tid info in jbd debug log 
This adds commit_tid argument in ext4_fc_update_stats()
so that we can add this information too in jbd_debug logs.
This is also required in a later patch to pass the commit_tid info in
ext4_fc_commit_start/stop() trace events.

1d2e2440c5 ext4: add transaction tid info in fc_track events 
This patch adds the transaction & inode tid info in trace events for
callers of ext4_fc_track_template(). This is helpful in debugging race
conditions where an inode could belong to two different transaction tids.
It also fixes the checkpatch warnings which says use tabs instead of
spaces.

78be0471da ext4: return early for non-eligible fast_commit track events 
Currently ext4_fc_track_template() checks, whether the trace event
path belongs to replay or does sb has ineligible set, if yes it simply
returns. This patch pulls those checks before calling
ext4_fc_track_template() in the callers of ext4_fc_track_template().

[ Add checks to ext4_rename() which calls the __ext4_fc_track_*()
  functions directly. -- TYT ]

8126b1c731 pstore: Don't use semaphores in always-atomic-context code 
pstore_dump() is *always* invoked in atomic context (nowadays in an RCU
read-side critical section, before that under a spinlock).
It doesn't make sense to try to use semaphores here.

This is mostly a revert of commit ea84b580b9 ("pstore: Convert buf_lock
to semaphore"), except that two parts aren't restored back exactly as they
were:

 - keep the lock initialization in pstore_register
 - in efi_pstore_write(), always set the "block" flag to false
 - omit "is_locked", that was unnecessary since
   commit 959217c84c ("pstore: Actually give up during locking failure")
 - fix the bailout message

The actual problem that the buggy commit was trying to address may have
been that the use of preemptible() in efi_pstore_write() was wrong - it
only looks at preempt_count() and the state of IRQs, but __rcu_read_lock()
doesn't touch either of those under CONFIG_PREEMPT_RCU.
(Sidenote: CONFIG_PREEMPT_RCU means that the scheduler can preempt tasks in
RCU read-side critical sections, but you're not allowed to actively
block/reschedule.)

Lockdep probably never caught the problem because it's very rare that you
actually hit the contended case, so lockdep always just sees the
down_trylock(), not the down_interruptible(), and so it can't tell that
there's a problem.

4d9237e32c io_uring: recycle apoll_poll entries 
Particularly for networked workloads, io_uring intensively uses its
poll based backend to get a notification when data/space is available.
Profiling workloads, we see 3-4% of alloc+free that is directly attributed
to just the apoll allocation and free (and the rest being skb alloc+free).

For the fast path, we have ctx->uring_lock held already for both issue
and the inline completions, and we can utilize that to avoid any extra
locking needed to have a basic recycling cache for the apoll entries on
both the alloc and free side.

Double poll still requires an allocation. But those are rare and not
a fast path item.

With the simple cache in place, we see a 3-4% reduction in overhead for
the workload.

Use folio->index instead of folio_index() because there's no way we're
writing a page from the swapcache to a directory.

83a44a4f47 x86: Remove toolchain check for X32 ABI capability 
Commit 0bf6276392 ("x32: Warn and disable rather than error if
binutils too old") added a small test in arch/x86/Makefile because
binutils 2.22 or newer is needed to properly support elf32-x86-64. This
check is no longer necessary, as the minimum supported version of
binutils is 2.23, which is enforced at configuration time with
scripts/min-tool-version.sh.

Remove this check and replace all uses of CONFIG_X86_X32 with
CONFIG_X86_X32_ABI, as two symbols are no longer necessary.

[nathan: Rebase, fix up a few places where CONFIG_X86_X32 was still
         used, and simplify commit message to satisfy -tip requirements]

2e7e80f7e7 fs: Convert is_partially_uptodate to folios 
Since the uptodate property is maintained on a per-folio basis, the
is_partially_uptodate method should also take a folio.  Fix the types
at the same time so it's clear that it returns true/false and takes
the count in bytes, not blocks.

744e6c8ada xfs: constify xfs_name_dotdot 
The symbol xfs_name_dotdot is a global variable that the xfs codebase
uses here and there to look up directory dotdot entries.  Currently it's
a non-const variable, which means that it's a mutable global variable.
So far nobody's abused this to cause problems, but let's use the
compiler to enforce that.
