This is intended to rework a bit the perf event scheduling to guarantee a real priority of the pinned events over the volatile ones. This patchset handles such priority on task tick time only. But if the idea is agreed, I could expand that to every task event sched-in calls to guarantee the priority in every event rescheduling time. Thanks.
