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
