Subject: Scheduler question in __wake_up_common() - Real Time Apps
Date: Mon, 28 Feb 2005 13:30:36 -0500 [thread overview]
Message-ID: <20050228183036.GA22914@calma.pair.com> (raw)
I have a question about the implementation in __wake_up_common() that I'm
hoping someone might know the background on. This function wakes up
a specified number of tasks for a wait_queue. I'm wondering why it doesn't
wake up the tasks in priority order, so that for things following wake-one
semantics high priority tasks get woken up before lower priority tasks.
The only thing I can think of off the top of my head is that it simplifies the
O(1) implementation, but I'm wondering if maybe there is something else.
Thanks,
Chad
