I tried it, but it did not change the results unfortunately. I just
ran the test (prog1) with kernel 2.1.120 with you patch profiling
patch. So I have a few traces: one with the "unaltered" system and 3
with the "altered" system.
Do you want me to email you directly the results or put them
somewhere ?
Regards,
Claude
P.S.: your patch works well with 2.1.120 SMP.
