Pull btrfs fixes from David Sterba:
 "Regression fixes in zone activation:

   - move a loop invariant out of the loop to avoid checking space
     status

   - properly handle unlimited activation

  Other 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"
