[PATCHSET,0/3] Cleanup and improve MSG_RING performance

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.
