CentOS will not make changes to the distro kernel because it aims to be 100% binary compatible (including bugs). However, it you submit the patch you have, it might be included in the centosplus kernel. I suggest you open a report at http://bugs.centos.org with a detailed description of the problem and upload your patch. Another thing you want to try is to open a bugzilla upstream. If the patch is incorporated in the upstream kernel, it will then be in the CentOS kernel. The kABI fix you mentioned is not a problem. It is just a note. You can still build custom kernels by following the instructions on the Wiki. Akemi
