Abstract
Systems and methods for waking up waiting processing streams in a manner that reduces the number of spurious wakeups. An example method may comprise: assigning a first identifier of a sequence of identifiers to a processing stream in a waiting state; receiving a wakeup signal associated with a second identifier of the sequence of identifiers; comparing, by a processing device, the first identifier with the second identifier; and waking the processing stream responsive to determining, in view of comparing, that the processing stream began waiting prior to an initiation of the wakeup signal.
