[PATCH 1/9] slab: add unlikely macro to help compiler

slab_should_failslab() is called on every allocation, so to optimize it is reasonable. We normally don't allocate from kmem_cache. It is just used when new kmem_cache is created, so it's very rare case. Therefore, add unlikely macro to help compiler optimization. Signed-off-by: Joonsoo Kim diff
