[PATCH V2 2/3] sched: Move deadline container_of() helper functions into sched.h
From: Daniel Bristot de Oliveira
Date: Mon Mar 28 2016 - 12:51:19 EST
Move dl_task_of(), dl_rq_of_se() and rq_of_dl_rq() helper functions
from kernel/sched/deadline.c to kernel/sched/sched.h, so they
can be used on other scheduler files.
