Information about all Linux kernel developer mailing lists is provided on [[https://subspace.kernel.org/vger.kernel.org.html|vger.kernel.org]]. If there are questions about LKML, please consider [[http://vger.kernel.org/lkml/|LKML FAQs]] first.

<WRAP left round important>

All patches against the RT tree should be [[realtime:communication:send_rt_patches | posted]]
to LKML and CCing linux-rt-devel. 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.

The linux-rt-users list is intended for users who want to ask questions about using the -rt patch set.

If you are interested in sending patches for improvements or bug fixes for RT, please see [[realtime:communication:send_rt_patches | Send Patches for RT]].
