Merge branch 'for-4.10-fixes' of git://git./linux/kernel/git/tj/percpu

Pull percpu fix from Tejun Heo:
 "Douglas found and fixed a ref leak bug in percpu_ref_tryget[_live]().

  The bug is caused by storing the return value of atomic_long_inc_not_zero()
  into an int temp variable before returning it as a bool. The interim
  cast to int loses the upper bits and can lead to false negatives. As
  percpu_ref uses a high bit to mark a draining counter, this can happen
  relatively easily.

  Fixed by using bool for the temp variable"
