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).
