[PATCH 0/3] mm/slub: Fix slabs_node return value

[Muchun Song <songmuchun@bytedance.com>]

The slabs_node() always return zero when CONFIG_SLUB_DEBUG is disabled.
But some codes determine whether slab is empty by checking the return
value of slabs_node(). As you know, the result is not correct. we move
the nr_slabs of kmem_cache_node out of the CONFIG_SLUB_DEBUG. So we can
get the corrent value returned by the slabs_node().

Muchun Song (3):
  mm/slub: Fix slabs_node return value when CONFIG_SLUB_DEBUG disabled
  mm/slub: Use node_nr_slabs() instead of slabs_node()
  mm/slub: Fix release all resources used by a slab cache
