Pull btrfs fixes from David Sterba:

 - in incremental send, fix invalid clone operation for file that got
   its size decreased

 - fix __counted_by() annotation of send path cache entries, we do not
   store the terminating NUL

 - fix a longstanding bug in relocation (and quite hard to hit by
   chance), drop back reference cache that can get out of sync after
   transaction commit

 - wait for fixup worker kthread before finishing umount

 - add missing raid-stripe-tree extent for NOCOW files, zoned mode
   cannot have NOCOW files but RST is meant to be a standalone feature

 - handle transaction start error during relocation, avoid potential
   NULL pointer dereference of relocation control structure (reported by
   syzbot)

 - disable module-wide rate limiting of debug level messages

 - minor fix to tracepoint definition (reported by checkpatch.pl)

  btrfs: drop the backref cache during relocation if we commit
  btrfs: also add stripe entries for NOCOW writes
  btrfs: send: fix buffer overflow detection when copying path to cache entry

While running checkpatch.pl against a patch that modifies the
btrfs_qgroup_extent event class, it complained about using a comma instead
of a semicolon:

  $ ./scripts/checkpatch.pl qgroups/0003-btrfs-qgroups-remove-bytenr-field-from-struct-btrfs_.patch
  WARNING: Possible comma where semicolon could be used
  #215: FILE: include/trace/events/btrfs.h:1720:
  +		__entry->bytenr		= bytenr,
		__entry->num_bytes	= rec->num_bytes;

  total: 0 errors, 1 warnings, 184 lines checked

So replace the comma with a semicolon to silence checkpatch and possibly
other tools. It also makes the code consistent with the rest.

Pull firewire updates from Takashi Sakamoto:
 "In the FireWire subsystem, tasklets have been used as the bottom half
  of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
  become available, and some developers have proposed replacing the
  tasklet with a BH workqueue.

  As a first step towards dropping tasklet use, the 1394 OHCI
  isochronous context can use regular workqueues. In this 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 normal workqueues are suitable,
  through BH workqueues are not.

  The replacement with a 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.

  Summary:

   - Replace tasklet with workqueue for isochronous context

   - Replace IDR with XArray

   - Utilize guard macro where possible

   - Print deprecation warning when enabling debug parameter of
     firewire-ohci module

   - Switch to nonatomic PCM operation"

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"
