[PATCH v2 1/7] sched/deadline: fix try to pull pinned dl tasks in pull algorithm

2015-05-12 Thread Wanpeng Li
Function pick_next_earliest_dl_task is used to pick earliest and pushable dl task from overloaded cpus in pull algorithm, however, it traverses runqueue rbtree instead of pushable task rbtree which is also ordered by tasks' deadlines. This will result in getting no candidates from overloaded cpus i
