[GIT PULL rcu/next] RCU commits for 4.6
From: Paul E. McKenney
Date: Mon Mar 07 2016 - 15:25:41 EST
Hello, Ingo,
Note that this series conflicts with some commits in Thomas Gleixner's
hotplug series and in Daniel Wagner's swait series, both of which are in
-tip. I have suggested conflict-resolution commits for Daniel's commits
(25f0d48a4299 "Merge commit 'abedf8e2419fb873d919dd74de2e84b510259339'
into wagi.2016.03.01a") and for Thomas's commits (dc96aeda643f "Merge
commit '27d50c7eeb0f' into wagi.2016.03.01a"), which you might find
useful. These merge commits pass rcutorture testing, 0day robot testing,
and -next testing.
The changes in this series include:
1. Documentation updates, including RCU data structure design-level
documentation.
https://lkml.org/lkml/2016/2/24/26
2. Miscellaneous fixes.
https://lkml.org/lkml/2016/2/24/34
3. Torture-test updates.
https://lkml.org/lkml/2016/2/24/50
As noted earlier, all of these changes have been subjected to 0day Test
robot and -next testing, and are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git for-mingo
