Subject: Behavior of poll() within a module
Date: Tue, 23 Oct 2001 08:53:04 -0400 (EDT)	[thread overview]
Message-ID: <Pine.LNX.3.95.1011023085214.9875A-100000@chaos.analogic.com> (raw)


What is the intended behavior of poll within a module when
two or more tasks are sleeping in poll? Specifically, when
wake_up_interruptible is executed from a module, are all
tasks awakened or is only one? If only one, is it the
first task to call poll/select or the last, which is awakened
first? 


Cheers,
Dick Johnson

    I was going to compile a list of innovations that could be
    attributed to Microsoft. Once I realized that Ctrl-Alt-Del
    was handled in the BIOS, I found that there aren't any.
