[PATCH 00/16] rcu: Some minor fixes and cleanups

[Pranith Kumar]

Hi Paul,

This is a series of minor fixes and cleanup patches which I found while studying
the code. All my previous pending (but not rejected ;) patches are superseded by
this series, expect the rcutorture snprintf changes. I am still waiting for you
to decide on that one :)

These changes have been tested by the kvm rcutorture test setup. Some tests give
me stall warnings, but otherwise have SUCCESS messages in the logs. But those
are occuring even without these changes with the tip paul/rcu/dev. May be it is
because I am running them for a duration of 4 minutes each only?
