Subject: [S+Q Cleanup3 0/6] SLUB: Cleanups V3
Date: Thu, 19 Aug 2010 15:33:24 -0500 [thread overview]
Message-ID: <20100819203324.549566024@linux.com> (raw)
V1->V2: Fixes as discussed with David.
V2->V3: More deeper fixes. Return pointer to kmem_cache from create_kmalloc_cache.
These are just the 6 remaining cleanup patches (after the 2.6.36 merge
got the other in) in preparation for the Unified patches.
I think it may be best to first try to merge these and make sure that
they are fine before we go step by step through the unification patches.
I hope they can go into -next.
Patch 1
Uninline debug functions in hot paths. There is no point of the compiler
folding them in because they are typically unused.
Patch 2
Remove dynamic creation of DMA caches and create them statically
(will be turned dynamic by patch 4 but will then always be preallocated
on boot and not from the hotpath)
Patch 3
Remove static allocation of kmem_cache_cpu array and rely on the
percpu allocator to allocate memory for the array on bootup.
Patch 4
Remove static allocation of kmem_cache structure for kmalloc and friends.
Patch 5
Extract hooks for memory checkers.
Patch 6
Move gfpflag masking out of the allocator hotpath
