Changes since v0.12 (the last release posted) include: - refactored, simplified network message library - now strictly client/server - simplified callback vector - fewer memory allocations - improved client/monitor protocol - fixed EOF vs (short) read behavior with multi-client sharing - cleanup, refactoring in osd reply code - bug fixes The biggest change is in the message library. A whole class of potential memory allocations have been removed, the groundwork has been laid to reserve memory for incoming messages, and lots of code got removed in the process. This is mainly motivated by the desire to eliminate any memory allocations during writeback; we're pretty close to having that resolved. If there are other areas of concern (general or specific) with this patchset, please speak up. We would like to see this merged soon. What is the next step here?
