Subject: [PATCH 0/1] fix incorrect comment in kernel/sched/rt.c

I was reading rt.c and was looking at the code pertaining to allowing a
non-migratable task to preempt a migratable task of the same priority.
It appears to me that one of the comments describing when this will
happen is wrong.

It appears that preemption will only happen when the task is *not* about
to be otherwise preempted.  The comment appears to describe an older
version of the code, in which preemption would happen when the task *was*
about to be preempted, the opposite condition.
