I was looking over the RT patch and I had a couple of questions:
Is there a reason that the PREEMPT_LAZY code is not ifdef-ed out when
PREEMPT_LAZY is disabled. I can't see a reason to leave it in, it's
just dead code at that point. I'd be happy to do a patch to fix this.
Why does preempt_disable_rt() become a barrier when PREEMPT_RT is
disabled? Why isn't it just nothing?
Thanks,

Because I'm a lazy bastard and I fundamentaly hate #ifdefs :)
