  • d0aa7a70b   futex_requeue_pi optimization ... Browse Code »

    This patch provides the futex_requeue_pi functionality, which allows some
    threads waiting on a normal futex to be requeued on the wait-queue of a
    PI-futex.

    This provides an optimization, already used for (normal) futexes, to be used
    with the PI-futexes.

    This optimization is currently used by the glibc in pthread_broadcast, when
    using "normal" mutexes. With futex_requeue_pi, it can be used with
    PRIO_INHERIT mutexes too.

    RT-mutex tester: scriptable tester for rt mutexes, which allows userspace
    scripting of mutex unit-tests (and dynamic tests as well), using the actual
    rt-mutex implementation of the kernel.
