Hi,

Hi,

MSG_RING rolls its own task_work handling, which there's really no need
for. 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 +++++++++++++++++++++------------------------
