mm/slub: add slub_get_cpu_partial() helper
Add slub_get_cpu_partial() and dummy function to help improve get_partial_node(). It can help remove #ifdef of CONFIG_SLUB_CPU_PARTIAL and improve filling cpu partial logic. Signed-off-by: Xiongwei Song <xiongwei.song@windriver.com> Signed-off-by: Vlastimil Babka <vbabka@suse.cz>
