Just to underscore Arjan's point: non-mainline patches are very
actively discouraged at Red Hat. As time progresses the maintenance
cost of EACH non-mainline patch increases. Non-mainline patches do not
get the benefits of wide community testing, review, and feedback.
Further, Red Hat employees in my experience typically land patches in
the community _first_ -- witness my netdriver work (goes me -> Marcelo
-> RH), DaveM's net stack work, and Alan's -ac tree.
