Hey Pavel,

There are two reasons it didn't make it into 5.10 or 5.4:

1. It doesn't build on any of those kernels, and we haven't gotten a
backport we could apply.

2. There's a follow-up fix that happened soon after ( 40cdc509877b
("btrfs: skip reserved bytes warning on unmount after log cleanup
failure") ) which needs a backport on it's own.
