- locally enable -Wmaybe-uninitialized after fixing all warnings
I've pulled this, but I strongly suspect this change will get reverted.
I bet neither you nor linux-next is testing even _remotely_ a big chunk of the different compiler versions that are out there, and the reason flags like '-Wmaybe-uninitialized' get undone is because some random compiler version on some random config and target archiecture gives completely nonsensical warnings for odd reasons.
But hey, maybe the btrfs code is special.
Maybe it's too late for 6.3. So please fix this in 6.4 and backport it to 6.3 stable.
Fix for this warning is in 6.4 pull request, there's no CC:stable tag but we can ask to add it once the code lands in master.
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:
