Nope, cp 8.10 is not absolved yet.
It may be btrfs not honoring FIEMAP_FLAG_SYNC,
and/or it may be cp needing to handle FIEMAP_EXTENT_ENCODED
specially.
It would help if you ran `sync` before the copy,
to exclude that as a possible issue.
Also `filefrag -v` output for the file on
the compressed BTRFS file system would be helpful.
thanks,
P=E1draig.
