Possible optimization in NPTL ?

[Sebastien Decugis]

Hi all,

I've seen that everytime a new thread is created with a defined
scheduling policy, two syscalls are issued (sched_get_priority_min and
sched_get_priority_max). I was wondering if it wouldn't be worth caching
those values... I think those are constants (depending of the policy of
course), so couldn't we have a local copy (in user land) of the array
{policies/range} ?

Any thoughts?

Thanks,
Sebastien.
