I'm not sure why this would even be reported, as this patch has not been accepted
or acked or nothin', by anyone. In this particular case that raw performance drop
is because spinning is pretty much disabled by Ding's change. Totally expected for
the kind of workload unixbench triggers.
All this does is hurt lkml-searchability.
Thanks,
Davidlohr

Sorry for bothering. The purpose is FYI as in the original report email. We test patches posted to LKML, if we found some changes related to the patch, we will send out a report. Hope the reviewer could take that as information for his/her review if the report isn't totally nonsense. > In this particular case that raw performance drop > is because spinning is pretty much disabled by Ding's change.

For me, the 0day reports on LKML postings have been quite helpful. They
give the submitter immediate feedback on a number of issues, thus reducing
the number of rounds of review.
