From 91f47662dfaa5b459aebe13284c6c38db27350dc Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Tue, 6 Jan 2009 14:40:33 -0800 Subject: [PATCH] mm: hugetlb: remove redundant `if' operation At this point we already know that 'addr' is not NULL so get rid of redundant 'if'. Probably gcc eliminate it by optimization pass.
