    SubjectRe: [patch] sleep_on() done with cli() in the NFS code, 2.2.2
       Date: 	Tue, 2 Mar 1999 10:30:27 +0100 (CET)
    From: Ingo Molnar <mingo@chiara.csoma.elte.hu>

    there is one more place i found that does sleep_on() with cli(),
    this can lead to lockups under SMP. Are there any unsolved reports
    of lockups for NFS + SMP-2.2.2?

    That whole stretch of code is bogus, it should be using bh atomicity
    instead. The thing it is trying to be atomic against are events which
    are a result of packet arrival and perhaps timers as well.

    Later,
