    Subject[PATCH] ext3 lockup fix to lock-break-rml-2.4.18-1.patch
    Date
    Hi Robert,
    The following patch fixes an apparent mismerge of Andrew Morton's low
    latency work into the lock breaking patch. Without this fix,
    journal_commit_transaction() will loop forever, without making
    forward progress, if need_resched was set on entry.

    Base to which the patch was derived:

    linux.2.4.18.tar.bz2
    + sched-O1-2.4.18-pre8-K3.patch
    + preempt-kernel-rml-2.4.18-rc1-ingo-K3-1.patch
    + lock-break-rml-2.4.18-1.patch

    Regards,
    Joe
