nit:
the commit title refers to ceph_open() but the code changes are
pertaining to ceph_lookup()

Good catch.

I couldn't remember why we didn't fix this before as I remembered I have found this.

Thanks

Otherwise it looks good to me.

Instead of setting the no-key dentry in ceph_lookup(), use the new
fscrypt_prepare_lookup_partial() helper.  We still need to mark the
directory as incomplete if the directory was just unlocked.
