Actually, not exactly; simplifying a bit, in the NULL case they do:
and a comment on d_splice_alias says
Cluster filesystems may call this function with a negative,
hashed dentry. In that case, we know that the inode will be a
regular file, and also this will only occur during atomic_open.
I don't understand those callers. But I guess it would be easy enough
to handle in d_materialise_unique.
