It landed in master.

Hi Greg and stable team, could you please backport:
commit 8ba7d5f5ba931be68a94b8c91bcced1622934e7a upstream
("btrfs: fix uninitialized variable warnings")
to v6.3 to fix gcc (10, 9, 7) build error?
The fs/btrfs/volumes.c hunk won't apply cleanly, but it can auto-merge:
$ git cherry-pick 8ba7d5f5ba931be68a94b8c91bcced1622934e7a
Auto-merging fs/btrfs/volumes.c
