    SubjectRe: [BENCHMARK] I/O regression after 2.6.0-test5

    Sorry, this patch didn't fix our performance problems. Mary just
    finished running dbt2 on test8 with your patch:

    NOTPM kernel scheduler
    965 2.6.0-test8-np AS
    1632 2.6.-test6-mm4 deadline

    This is an 8-way system with DAC960 and 12 LUNs, using raw devices.
    That's still quite a sizeable drop.
