Public bug reported:
It is resolute, btrfs root is mounted noatime,compress,nossd and it gets
corrupted instantly. Every writes to a filesystem gets corrupted

dm-10): zlib decompression failed, error -3 root 5 inode 121426308
offset 0
btrfs scrub start ... doesn't (always) find it. The data is corrupted on the
compressed chunk i guess, not the extent itself.
The problem occurs with 7.0.0-10 - happens in every mount, and it was
(sadly) reproduced on 2 machines. It is not hardware related.
Running 6.19 and restoring (from backup) the corrupted files solved the
problem.
This is very serious if you use btrfs with compression, I tought I have
a bad luck with a bad kernel release, but no, this is in the resolute
for at least a week.
