Subject: [PATCH] mm: slub: Declare slab_owner_ops only when SLUB DEBUG is
 enabled

Declare the ops struct and corresponding callbacks only when
SLUB_DEBUG is enabled.
Currently, the ops is defined only under
MINIDUMP_PANIC_DUMP config but the variables it uses are protected
under SLUB_DEBUG as well.
