[PATCH 0/6] timers nohz updates preview for 3.11

From: Frederic Weisbecker
Date: Wed Jun 12 2013 - 10:02:52 EST


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:



Frederic Weisbecker (5):
sched: Disable lb_bias feature for full dynticks
watchdog: Register / unregister watchdog kthreads on sysctl control
watchdog: Boot-disable by default on full dynticks
rcu: Prevent CPU from stopping tick if awaited for quiescent state report
nohz: Remove obsolete check for full dynticks CPUs to be RCU nocbs

Steven Rostedt (1):
nohz: Warn if the machine can not perform nohz_full
