            adilger, thanks for checking in here. Yes, this is obsolete. I've closed it.
            simmonsja, you should also abandon https://review.whamcloud.com/c/fs/lustre-release/+/4916.

            presumably this patch and ticket are obsolete at this point?

            Initial patch is at http://review.whamcloud.com/#change,4916. Warning this is my first fray into SMP lnet programming so this is a basic first run to ensure I got the principles done right. More work will be added with time.
