From 5295a74cc0bcf1291686eb734ccb06baa3d55c1a Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Wed, 1 Feb 2006 03:05:48 -0800 Subject: [PATCH] slab: reduce inlining From: Manfred Spraul 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.
