[Xen-devel] [PATCH v2 3/3] xen: RCU: make the period of the idle timer adaptive.

Basically, if the RCU idle timer, when (if!) it fires, finds that the grace period isn't over, we increase the timer's period (i.e., it will fire later, next time). If, OTOH, it finds the grace period is already finished, we decrease the timer's period (i.e., it will fire a bit earlier next time).
