sched/dl: Support sched_stat_runtime tracepoint for deadline sched class
The runtime of a DL task has already been there, so we only need to add a tracepoint. One difference between fair task and DL task is that there is no vruntime in dl task. To reuse the sched_stat_runtime tracepoint, '0' is passed as vruntime for DL task. The output of this tracepoint for DL task as follows, top-36462 [047] d.h. 6083.452103: sched_stat_runtime: comm=top pid=36462 runtime=409898 [ns] vruntime=0 [ns] Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lore.kernel.org/r/20210905143547.4668-8-laoar.shao@gmail.com
