Hello, Ingo,

This series contains the following changes:

1. Documentation updates. Just some simple changes, no design-level
additions. I guess that means two for the next merge window...

http://lkml.kernel.org/g/20160615213847.GA3610@xxxxxxxxxxxxxxxxxx

2. Miscellaneous fixes.

http://lkml.kernel.org/g/20160615214550.GA4931@xxxxxxxxxxxxxxxxxx

3. Torture-test updates.

http://lkml.kernel.org/g/20160615220924.GA7877@xxxxxxxxxxxxxxxxxx

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
