New RBD PTL

Hey all, A couple months ago Jason Dillaman, our long-time RBD tech lead, moved on from his job at Red Hat working on Ceph to a new opportunity. This left a hole in the team we needed to fill on short notice, and because I was asked to backfill Jason in Red Hat's internal affairs I also took on some of his upstream tech lead duties on a fill-in basis — I don't think this was ever discussed on the lists but it came up in CDM and some meetings. However, we've had more time since then to converse among the relevant people and I am happy to announce that Ilya Dryomov has agreed to take over the PTL role for RBD. Many of you know Ilya for his work throughout Ceph's kernel clients (including especially the RBD module) and sometime wrangling of security issues in our messaging layers, and I look forward to him expanding his leadership role in the project. Thanks! -Greg
