I have to be honest, I am not too thrilled at the idea of taking a patch
set which has been rejected upstream into ARK. RHEL is one thing, with
he guarantee of a stable ABI. there is a lot less churn. This tree
merges with the linus tree daily, and will continue to do so long after
RHEL is branched off to be it's own thing. A patch which has been
rejected upstream will have to be maintained and merge issues dealt with
indefinitely.
