    SubjectRe: [patch] voluntary-preempt-2.6.8-rc3-O4

    i've uploaded a new version of the preempt-timing patch:

    http://redhat.com/~mingo/voluntary-preempt/preempt-timing-on-2.6.8-rc3-O4.patch

    this patch fixes a number of false positives and false negatives. In
    particular it fixes the idle-task false positives, and it now correctly
    measures preemption delays in softirq and hardirq contexts and in
    bh-disabled process contexts. Maybe this sheds a light on some of the
    more mysterious delays that we've seen. (and which were never directly
    measured before.)

    (the patch also got alot simpler, which should help portability.)
