Merge tag 'for-5.18-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs fixes from David Sterba:

 - 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

* tag 'for-5.18-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
  btrfs: prevent subvol with swapfile from being deleted
  btrfs: do not warn for free space inode in cow_file_range
  btrfs: avoid defragging extents whose next extents are not targets
  btrfs: fix fallocate to use file_modified to update permissions consistently
  btrfs: remove device item and update super block in the same transaction
  btrfs: fix qgroup reserve overflow the qgroup limit
  btrfs: zoned: remove left over ASSERT checking for single profile
  btrfs: zoned: traverse devices under chunk_mutex in btrfs_can_activate_zone
