[GIT PULL] Btrfs fixes for 6.13-rc3

[GIT PULL] Btrfs fixes for 6.13-rc3

[David Sterba]

Hi,

please pull 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 is known and fixed for some time but I've delayed
it to give it more testing. More details about that below.

Please pull, thanks.

- 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
