From 84778472e1b6a27a8931712c40e8cf31143c8f6c Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Wed, 2 Sep 2015 01:28:44 -0700 Subject: [PATCH] sched: Export sched_setscheduler_nocheck The new locktorture rtmutex_lock tests exercise priority boosting, which means that they need to set some tasks to real-time priority. To do this, they use sched_setscheduler_nocheck(). However, this is not exported to modules, which results in the following error when building locktorture as a module: ERROR: "sched_setscheduler_nocheck" [kernel/locking/locktorture.ko] undefined! This commit therefore adds an EXPORT_SYMBOL_GPL() to allow this function to be invoked from locktorture when built as a module.
