What is the plan for this series?

We are currently discussing locking changes that might affect 2/3, but
I'd still consider this patch and the overall series as an improvement
over the current status (1/3 is a fix to the code) and I'd really like
future changes to be based on this series...

I expected this series to go via "-rcu -> tip -> ..."; 2/3 had Peter's
Ack, but 1/3 and 3/3 are missing any comments (or tags): please let me
know if any action on the series is required from me (the series still
applies on the latest "dev" branch of -rcu).
