These patches are backport for the 5.18 branch.

They all fixes zoned mode related issued on btrfs.

The patch 3 looks different from upstream commit b3a3b0255797 ("btrfs:
zoned: drop optimization of zone finish") as a refactoring patch is not
picked into the stable branch. But, essentially, they do the same thing
which always zone finish the zones after (nearly) full write.

The v2 just amend a line to add a missing variable declaration.

Naohiro Aota (3):
  btrfs: zoned: prevent allocation from previous data relocation BG
  btrfs: zoned: fix critical section of relocation inode writeback
  btrfs: zoned: drop optimization of zone finish
