[8], [9] Hi, I'm planning on reading through this patch set; but before I do, since it's been several months and it's a non-trivially sized series, I just wanted to confirm that this is the latest revision of the RFC that you'd like comments on. Or, if there's a more recent series that I've missed, I would be grateful for a pointer to it. Thanks, Connor
