Subject: Couple of questions about details of the RT patch
Date: Thu, 06 Feb 2014 12:17:11 -0600 [thread overview]
Message-ID: <52F3D1A7.8020809@mvista.com> (raw)
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,
-corey
