From 881db7fb03a77af0bcd460fd1de1f4062d5c18fe Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Wed, 1 Jun 2011 12:25:53 -0500 Subject: [PATCH] slub: Invert locking and avoid slab lock Locking slabs is no longer necesary if the arch supports cmpxchg operations and if no debuggin features are used on a slab. If the arch does not support cmpxchg then we fallback to use the slab lock to do a cmpxchg like operation. The patch also changes the lock order. Slab locks are subsumed to the node lock now. With that approach slab_trylocking is no longer necessary. Signed-off-by: Christoph Lameter Signed-off-by: Pekka Enberg --- Reading git-format-patch failed
