I see.  Thanks.

I have applied and pushed your patch as the two attached git patches
(if you could send your changes in "git format-patch" format in
future, ideally with a ChangeLog entry too, that would streamline
things for me).

Thank you for this contribution to GNU findutils.

Thanks for the pointer.   The semantics that Gen Zhang was relying on
(processing all entries in a directory at once) were never guaranteed

If you'd like to supply a backported "format-patch" patch against the
4.4.x tree, I can apply that too.
