Getting the patch into the centosplus kernel is as easy as filing a request at http://bugs.centos.org . :) Regarding the upstream kernel, you don't have to be a customer to report a bug at http://bugzilla.redhat.com . In this case, because the patch is already in mainline kernel, there is some good chance that it is picked up by Red Hat. Akemi
