From f139caf2e89713687514d9db847a4fa2e29c87a2 Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Fri, 12 Sep 2014 17:40:54 +0400 Subject: sched, cleanup, treewide: Remove set_current_state(TASK_RUNNING) after schedule() schedule(), io_schedule() and schedule_timeout() always return with TASK_RUNNING state set, so one more setting is unnecessary. (All places in patch are visible good, only exception is kiblnd_scheduler() from: drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c Its schedule() is one line above standard 3 lines of unified diff) No places where set_current_state() is used for mb().
