Tags: upstream patch
Justification: causes serious data loss
Apparently there was a longer existing data corruption bug in btrfs,
AFAIU it happened when compression was used together with holes in data
and there was *no* recognition by checksumming.
Seems some movement got into this the last days and a patch may have
been found fixing the issue.
Due to potential silent data corruptpion it makes perhaps sense to
cherry pick that fix (maybe waiting for confirmation from upstream
whether it's the final one) instead of waiting for it being released
in some upcoming stable release?
