Quite likely, other filesystems does have an inode flag that is set when
file has been compressed and simply report that in the foo_getattr()
callback. Looking at bcachefs I supose that we need to figure out if the
inode is v3 and then unpack the v3 info to get to the compressed flag,
you probably know best how to do that.
