From 6f7bd76f05eb2bfbb48d58c0408a50a7e16b2423 Mon Sep 17 00:00:00 2001 From: Rakib Mullick Date: Thu, 26 May 2011 16:26:00 -0700 Subject: [PATCH] kernel/profile.c: remove some duplicate code from profile_hits() profile_hits() has a common check for prof_on and prof_buffer regardless of SMP or !SMP. So, remove some duplicate code by splitting profile_hits into two.
