    SubjectRe: [PATCH] set_cpus_allowed() for 2.4

    Hi Everyone,

    I ran into a lockup with the O(1) scheduler back in August and
    exchanged email with Andrea. I tried a couple of his patches.
    They prevented the lockup but it was still easy to have the
    X server exiled to the inactive array for seconds at a time.
    This got me started working on a patch to make the schedule
    more fair.

    I posted a patch archive here:
    http://marc.theaimsgroup.com/?l=linux-kernel&m=103508412423719&w=2

    It fixes fairness but breaks nice(2). Rik van Riel has a
    patch here which builds on my patch which fixes this:
    http://marc.theaimsgroup.com/?l=linux-kernel&m=103651801424031&w=2

    I tested the combination of these patches with linux-2.5.48 and
    it seems well behaved:-)

    I found this problem with the LTP waitpid06 test. It actually
    produced a live-lock. See this mail:
    http://marc.theaimsgroup.com/?l=linux-kernel&m=103133744217082&w=2

    I have been distracted by Posix timers but I plan to get back
    finish this.
