Hi,
what happen when you call wake_up_interruptible and there are no task waiting on that wait queue right then.
But say after some time a task comes along and start waiting (after the wake_up_interruptible is called).
Would that task be not wait at all because there was a pending wake up
What i'm looking for is a mechanism where by any old wake if not acted upon are lost. so in the above mention case if a task come along and waits after a wake has been sent, it continues to wait until a next wake up is sent.
feel free to ask me if there is some more clarification required.
TIA
fundu
