Subject: [PATCH 0/5] optimization, clean-up, correctness about fair.c

There is no unified subject for this patchset.

Patch 1 is for removing one division operation with multiplication.
Patch 2,3 is for clean-up related to load_balance(), there is improvement
in terms of code size and IMO, readability may be also improved.
Patch 4,5 is for correctness about sched_slice()

Feel free to give a comment for this patchset.

It's based on v3.9-rc4 and top of my previous patchset. But, perhaps,
it may not really depend on my previous patchset. :)

"[PATCH v2 0/6] correct load_balance()"

Thanks.

Joonsoo Kim (5):
  sched: remove one division operation in find_buiest_queue()
  sched: factor out code to should_we_balance()
  sched: clean-up struct sd_lb_stat
  sched: don't consider upper se in sched_slice()
  sched: limit sched_slice if it is more than sysctl_sched_latency
