Rather, it should use the generic io_uring infrastructure for this. Add a helper for remote execution, and switch over MSG_RING to use it. This both cleans up the code, and improves performance of this opcode considerably. io_uring/io_uring.c | 30 ++++++++++++++++------ io_uring/io_uring.h | 2 ++ io_uring/msg_ring.c | 62 +++++++++++++++++++++------------------------ 3 files changed, 53 insertions(+), 41 deletions(-) Changes since v2: - Ensure fd install locking is correct
