Commit c65c1877bd68 ("slub: use lockdep_assert_held") incorrectly required

taken when kmem_cache_debug(s), since that's the only time it actually
does anything.

Require that the lock only be taken under such a condition.

You may add a "Tested-by: Larry Finger <Larry.Finger@xxxxxxxxxxxx>". The patch cleans up the splat on my system. Thanks for the quick response.
