Subject: [RFC PATCH 0/3] Series short description

Hi Ingo, Steven, Peter,
  This series applies roughly to mainline as an enhancement to the sched_rt
  logic.  Peter and I were discussing some of the unecessary overhead in
  pull_rt_tasks() via IRC, and this is my RFC attempt to address the problem.

  I have built/booted this on a 4-way C2D Xeon box and it passes preempt-test.

  Comments, please.

  -Greg

Gregory Haskins (3):
      sched: use highest_prio.next to optimize pull operations
      sched: use highest_prio.curr for pull threshold
      sched: track the next-highest priority on each runqueue
