It would be good to rename these to match the macro names used in the
ext4 kernel patch accepted upstream.

Is this something that is fixed in a later patch? I don't recall the
details of why these two features do not work together... I can imagine
in the case of inline directories that there is additional complexity
in handling dirdata packed inside the inode xattr space, but for regular
files (i.e. most files in a filesystem) the dirdata and inline data
features are orthogonal and it would be useful to have both enabled.
Obviously not something to implement in this patch, but definitely
something that would be useful to have in a follow-on patch.
Cheers, Andreas
