Merge tag 'for-5.5-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
"A few more fixes that have been in the works during last twp weeks.
All have a user visible effect and are stable material:
- scrub: properly update progress after calling cancel ioctl, calling
'resume' would start from the beginning otherwise
- fix subvolume reference removal, after moving out of the original
path the reference is not recognized and will lead to transaction
abort
- fix reloc root lifetime checks, could lead to crashes when there's
subvolume cleaning running in parallel
- fix memory leak when quotas get disabled in the middle of extent
accounting
- fix transaction abort in case of balance being started on degraded
mount on eg. RAID1"
