From 5f201907dfe4ad42c44006ddfcec00ed12e59497 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 10 Dec 2009 10:56:29 +0100 Subject: hrtimer: move timer stats helper functions to hrtimer.c There is no reason to make timer_stats_hrtimer_set_start_info and friends visible to the rest of the kernel. So move all of them to hrtimer.c. Also make timer_stats_hrtimer_set_start_info a static inline function so it gets inlined and we avoid another function call. Based on a patch by Thomas Gleixner.
