    Ingo,

    With Mingming's patch to resolve the ext3 allocate-with-reservation
    latency, it looks like we are finally getting close to the lower limit
    that can be achieved with PREEMPT_DESKTOP. I've attached the trace of
    the lowest latency over several days of testing with
    2.6.12-rc3-RT-V0.7.46-02 + Mingming's patch. It's only 127 usecs, and
    IIRC you mentioned previously that this code path can't be made
    preemptible in !PREEMPT_RT.

    Since Mingming's patch will have to live in -mm for a while, can it be
    added to the RT patchset as well?
