All patches against the RT tree should be posted to LKML. CCing rt-users is fine, but development needs to happen on the main kernel development list because only a few developers/maintainers are subscribed to rt-users. Furthermore, the more patch discussion happens on LKML, the more it helps promote the willingness of other kernel developers to accept that CONFIG_PREEMPT_RT isn't going to go away, and will probably (hopefully!) be merged into mainline someday soon.
The linux-rt-users list is intended for users who want to ask questions about using the -rt patch set.
