Subject: [GIT PULL] Btrfs fixes for 5.18-rc2

Hi,

please pull the following fixes for btrfs, thanks.

- prevent deleting subvolume with active swapfile

- fix qgroup reserve limit calculation overflow

- remove device count in superblock and its item in one transaction so
  they cant't get out of sync

- skip defragmenting an isolated sector, this could cause some extra IO

- unify handling of mtime/permissions in hole punch with fallocate

- zoned mode fixes:
  - remove assert checking for only single mode, we have the DUP mode
    implemented

  - fix potential lockdep warning while traversing devices when checking
    for zone activation
