Subject: [PATCH 0/6] timers nohz updates preview for 3.11
Date: Wed, 12 Jun 2013 16:02:32 +0200 [thread overview]
Message-ID: <1371045758-5296-1-git-send-email-fweisbec@gmail.com> (raw)
Hi,
So here is a first batch of some patches I think could go for 3.11
Except for "rcu: Prevent CPU from stopping tick if awaited for quiescent state report"
which needs more thinking. I believe we can do more from the IPI to force a
quiescent state without the need to restart the tick.
For those who want to check through git:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
timers/core-preview
Thanks,
Frederic
