[RFC 0/4] sched/fair: Rebalance tasks based on affinity

[Jiri Olsa]

hi,
please consider this to be more of a question
for opinions on how to solve this issue ;-)

I'm following up on my previous post:
  http://marc.info/?t=145975837400001&r=1&w=2

The patchset is working for my testcase and our
other tests looks good so far, but I'm not sure
I haven't broken something else or used the right
wheel to implement this.

The issue itself and the fix are described in
changelog of patch 3/4.

thanks for any feedback,
jirka
