◆ readinessGenerations()

ReadinessGenerations InotifyInstance::readinessGenerations ( )

overridevirtual

Return source-serialized rising-edge sequences where available.

A source increments the corresponding sequence while holding the same lock which changes its readiness predicate. Consumers can then recover a drain/refill transition even if the two callback deliveries are reordered.

Reimplemented from ReadinessSource.
