From becfda68abca673d61d5cc953e8e099816db99d9 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Tue, 15 Mar 2016 14:55:06 -0700 Subject: slub: convert SLAB_DEBUG_FREE to SLAB_CONSISTENCY_CHECKS SLAB_DEBUG_FREE allows expensive consistency checks at free to be turned on or off. Expand its use to be able to turn off all consistency checks. This gives a nice speed up if you only want features such as poisoning or tracing.
