      sched: fix mysql+oltp regression · 77ae6513
      Mike Galbraith authored
      Defer commit 6d299f1b to the next release.
      
      Testing of the tip/sched/clock tree revealed a mysql+oltp regression
      which bisection eventually traced back to this commit in mainline.
      
      Pertinent test results:  Three run sysbench averages, throughput units
      in read/write requests/sec.

      Note: subsequent commits hide the majority of this regression until you
      apply the clock fixes, at which time it reemerges at full magnitude.
      
      We cannot see anything bad about the change itself so we defer it to the
      next release until this problem is fully analysed.
