Ingo,
Please pull the testing enhancements for full dynticks from:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git timers/nohz-help-testing
HEAD: cb41a29076e9f95547da46578d5c8804f7b8845d
This is on top of my previous pull request (the timers/nohz branch) and it is deemed to ease testing and help to diagnose failures:
* First patch enables CONFIG_RCU_NOCB_ALL when we have full dynticks to ease automatic testing of the feature. This should also further help simplifying the code. If users want more granularity in the future to set RCU nocbs and timekeeper masks, we can still step back and select CONFIG_RCU_NOCB_ALL only when we have CONFIG_NO_HZ_FULL_ALL. Note this will only have an effect on tip/master because that config is in core/rcu and not yet upstream.
* Second patch adds some tracepoints to dump the dynticks behaviour as I got many questions from user who don't know how to diagnose why the tick didn't stop on their settings.
Thanks.
