I doubt that it is too bad since various filesystems (including JFS
and CIFS) have always written over qstr->name in these dentries in
order to better handle case insensitive compares.   Other than trying
to remove the compiler warning recently (mainline throws the same
warning), I didn't see what changed other than now displaying a
warning.   I agree that it looks strange, but I also don't see a
trivial way to change it.  Any ideas on how to prevent the case of an
existing negative dentry from taking precedence? Creating more
dentries for these duplicates would seem like a worse idea.
