Merge tag 'for-6.13-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave...

Pull btrfs fixes from David Sterba:
 "A few more fixes. Apart from the one liners and updated bio splitting
  error handling there's a fix for subvolume mount with different flags.
  This was known and fixed for some time but I've delayed it to give it
  more testing.

   - fix unbalanced locking when swapfile activation fails when the
     subvolume gets deleted in the meantime

   - add btrfs error handling after bio_split() calls that got error
     handling recently

   - during unmount, flush delalloc workers at the right time before the
     cleaner thread is shut down

   - fix regression in buffered write folio conversion, explicitly wait
     for writeback as FGP_STABLE flag is currently a no-op on btrfs

   - handle race in subvolume mount with different flags, the conversion
     to the new mount API did not handle the case where multiple
     subvolumes get mounted in parallel, which is a distro use case"
