From 669d557d58abebcc1de06cf7f2686612df6adc5c Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Tue, 15 Apr 2014 10:54:41 +0530 Subject: [PATCH] tick-sched: Check tick_nohz_enabled in tick_nohz_switch_to_nohz() commit 27630532ef5ead28b98cfe28d8f95222ef91c2b7 upstream. Since commit d689fe222 (NOHZ: Check for nohz active instead of nohz enabled) the tick_nohz_switch_to_nohz() function returns because it checks for the tick_nohz_active flag. This can't be set, because the function itself sets it. Undo the change in tick_nohz_switch_to_nohz().
