From e3de300d1212b42aa9d0d6031b12fca06ac00dd9 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 15 Jan 2014 12:30:15 +0100 Subject: [PATCH] sched: Preserve the nice level over sched_setscheduler() and sched_setparam() calls Previously sched_setscheduler() and sched_setparam() would not affect the nice value of a task, restore this behaviour.
