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" * 'for-4.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu-refcount: fix reference leak during percpu-atomic transition
