* kmem_cache hardening and performance improvementsBrian Behlendorf2009-01-306-496/+1025
| | | | | | | | | | | | | | | | | | | | | | | | | - Added slab work queue task which gradually ages and free's slabs from the cache which have not been used recently. - Optimized slab packing algorithm to ensure each slab contains the maximum number of objects without create to large a slab. - Fix deadlock, we can never call kv_free() under the skc_lock. We now unlink the objects and slabs from the cache itself and attach them to a private work list. The contents of the list are then subsequently freed outside the spin lock. - Move magazine create/destroy operation on to local cpu. - Further performace optimizations by minimize the usage of the large per-cache skc_lock. This includes the addition of KMC_BIT_REAPING bit mask which is used to prevent concurrent reaping, and to defer new slab creation when reaping is occuring. - Add KMC_BIT_DESTROYING bit mask which is set when the cache is being destroyed, this is used to catch any task accessing the cache while it is being destroyed. - Add comments to all the functions and additional comments to try and make everything as clear as possible. - Major cleanup and additions to the SPLAT kmem tests to more rigerously stress the cache implementation and look for any problems. This includes correctness and performance tests. - Updated portable work queue interfaces
