**调用者**
名称	描述
deactivate_slab	Remove the cpu slab
__slab_free	Slow path handling. This may still be called frequently since objects* have a longer lifetime than the cpu slabs in most processing loads.* So we still attempt to reduce cache line usage. Just take the slab* lock and free the item
free_partial	Attempt to free all partial slabs on a node.* This is called from __kmem_cache_shutdown(). We must take list_lock* because sysfs file might still access partial list after the shutdowning.
__kmem_cache_shrink	kmem_cache_shrink discards empty slabs and promotes the slabs filled* up most to the head of the partial lists. New allocations will then* fill those up and thus they can be removed from the partial lists.* The slabs with the least items are placed last
