Small naming suggestion: 'volatile' is a C keyword and rarely used
outside of that context in the kernel, which makes this function name a
bit confusing.
So instead of pinned/volatile, a pinned/flexible naming would be more
readable, i.e. __perf_event_sched_in_flexible() or so.
Also, most of the static functions in kernel/perf_event.c could lose
their perf_event_ prefix - we already know it's a perf thing, right?
That will shorten quite a few function names there.
These functions would turn into __sched_in_pinned()/__sched_in_flexible().
Agreed?
Ingo
