It is similar to a reader/writer lock, and it does protect the wake state. The writer, the suspend code, blocks until all the readers release their lock. If there are no readers after suspending all the drivers, the wake state changes. Since the readers can only run when in the awake state, they never block. -- Arve Hjønnevåg _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
