[PATCH] slab: reduce inlining
From: Manfred Spraul <manfred@colorfullife.com> Reduce the amount of inline functions in slab to the functions that are used in the hot path: - no inline for debug functions - no __always_inline, inline is already __always_inline - remove inline from a few numa support functions.
