X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84778472e1b6a27a8931712c40e8cf31143c8f6c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
