Subject: sched,powercap: Convert to sched_set_fifo*()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c3f47cf940efacaa8fab50973dc98f369c2066ff;p=linux.git

sched,powercap: Convert to sched_set_fifo*()

Because SCHED_FIFO is a broken scheduler model (see previous patches)
take away the priority field, the kernel can't possibly make an
informed decision.

Effectively no change.
