Merged
Conversation
Specifies a single session-owned io_uring shared by all concurrent file transfers. Covers the per-batch ring baseline, ownership trade offs (Arc<Mutex<Ring>> vs single-thread submitter), SQ partitioning and the registered fd table, the dispatcher concurrency model, the comparison with the #1409 ring pool, and a five-step migration plan. Cites task #1060.
