Hello,
Scenario:
Currently running [task1] boosts a priority (lowers a static_prio) of
[task2] via { setpriority -> set_user_nice } and [task2] happens to be
in the "expired" array at the moment.
According to the set_user_nice(), "delta" is negative (the prio is
boosted) and, hence, resched_task(rq->curr) is called.
As the [task2] is in the "expired" array and there are still tasks (at
least [task1]) in the "active" one, the triggered reschedule is just
useless (e.g. gets control back to [task1]).
Am I missing something?
The same is applicable to rt_mutex_setprio().
Of course, not a big deal, but it's easily avoidable, e.g. (delta < 0
&& array == rq->active).
Thanks in advance for any comments.
