Type:int

Parameter:

Type	Parameter	Name
struct kmem_cache *	s

**Caller**
Name	Describe
fixup_red_left
deactivate_slab	Remove the cpu slab
___slab_alloc	Slow path. The lockless freelist is empty or we need to perform* debugging duties.* Processing is still very fast if new objects have been freed to the* regular freelist. In that case we simply take over the regular freelist
__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
