    SubjectRe: [patch] voluntary-preempt-2.6.8.1-P0

    doh - i think i found a brown-paperbag bug.

    could you change this code in kernel/sched.c:

    int __sched voluntary_resched(void)
    {
    #ifdef CONFIG_DEBUG_SPINLOCK_SLEEP
    __might_sleep(__FILE__, __LINE__);
    #endif
    if (kernel_preemption || !voluntary_preemption)
    return 0;

    to:

    int __sched voluntary_resched(void)
    {
    #ifdef CONFIG_DEBUG_SPINLOCK_SLEEP
    __might_sleep(__FILE__, __LINE__);
    #endif
    if (!voluntary_preemption)
    return 0;

    Does the mlockall xrun still occur?
