[PATCH] slab: consolidate code to free slabs from freelist
Post and discussion:
http://marc.theaimsgroup.com/?t=115074342800003&r=1&w=2
Code in __shrink_node() duplicates code in cache_reap()
Add a new function drain_freelist that removes slabs with objects that are
already free and use that in various places.
This eliminates the __node_shrink() function and provides the interrupt
holdoff reduction from slab_free to code that used to call __node_shrink.
