test9-pre5+t9p2-vmpatch VM deadlock during write-intensive workload

i'm still getting VM related lockups during heavy write load, in test9-pre5 + your 2.4.0-t9p2-vmpatch (which i understand as being your last VM related fix-patch, correct?). Here is a histogram of such a lockup: 1 Trace; 4010a720 <__switch_to+38/e8> 5 Trace; 4010a74b <__switch_to+63/

yep this has done the trick, the deadlock is gone. I've attached the full VM-fixes patch (this fix included) against vanilla test9-pre5. Ingo --- linux/fs/buffer.c.orig Fri Sep 22 02:31:07 2000 +++ linux/fs/buffer.c Fri Sep 22 02:31:13 2000 @@ -706,9 +706,7 @@ static void re
