Mungerjiang 6554d7dccd locking/qspinlock: Introduce the shuffle reduction optimization into CNA 
This performance optimization chooses probabilistically to avoid moving
	threads from the main queue into the secondary one when the secondary queue
	is empty.

	It is helpful when the lock is only lightly contended. In particular, it
	makes CNA less eager to create a secondary queue, but does not introduce
	any extra delays for threads waiting in that queue once it is created.
