slub: do not fail if we cannot register a slab with sysfs
Do not BUG() if we cannot register a slab with sysfs. Just print an error. The only consequence of not registering is that the slab cache is not visible via /sys/slab. A BUG() may not be visible that early during boot and we have had multiple issues here already. Signed-off-by: Christoph Lameter <clameter@sgi.com> Acked-by: David S.
