I second this. _Any_ kernel development that is new must be discussed on
LKML. Sure, you can do the initial prototypes on a smaller mailing list,
but once you have that prototype ready, it should go to LKML. This was the
problem with Xen. The -rt patch was developed on LKML and even though
there's a lot more to get in, a lot already has. The reason is that all
development was done on the kernel mailing list.
