Revision 9d514262425691dddf942edea8bc9919e66fe140 authored by Wanpeng Li on 13 May 2015, 06:01:03 UTC, committed by Ingo Molnar on 19 June 2015, 08:06:46 UTC
This patch adds a check that prevents futile attempts to move DL tasks
to a CPU with active tasks of equal or earlier deadline. The same
behavior as commit 80e3d87b2c55 ("sched/rt: Reduce rq lock contention
by eliminating locking of non-feasible target") for rt class.
