Abstract
A technique includes monitoring for a quiescent state by checking first quiescent state criteria that are indicative of a CPU having no task running inside an RCU read-side critical section that could be affected by destructive-to-reader actions. If the quiescent state has been reached, a check may be made for the existence of a condition that is indicative of a requirement to satisfy one or more additional quiescent state criteria before reporting the quiescent state on behalf of the CPU. If the condition is detected, reporting of the quiescent state may be deferred until the one or more additional quiescent state criteria are satisfied. The quiescent state may then be reported if it is useful and safe to do so.
