[GIT PULL] Btrfs fixes for 5.18-rc6, part 2

[David Sterba]

Hi,

a few more regular fixes and regression fixes. Please pull, thanks.

- regression fixes in zone activation:
  - move a loop invariant out of the loop to avoid checking space status

  - properly handle unlimited activation

- fixes:
  - for subpage, force the free space v2 mount to avoid a warning and
    make it easy to switch a filesystem on different page size systems

  - export sysfs status of exclusive operation 'balance paused', so the
    user space tools can recognize it and allow adding a device with
    paused balance

  - fix assertion failure when logging directory key range item

----------------------------------------------------------------
