Note that the dirdata feature patches have not landed, and I've
expressed concerns of this patch set[1].

[1] https://lore.kernel.org/all/[email protected]/

From manual code inspection, the dirdata patch was never changing how
the data was stored.  So before we land the xfstests changes, could
you please add support in debugfs to set and get the dirdata stored
for a directory entry, and then change the test to actually _validate_
that when enabling encryption + casefold + dirdata, that the encrypted
hash is stored as a dirdata attribute?

Thanks,
