Subject: io_uring usage (ordering of commands)
Date: Mon, 31 Mar 2025 10:38:08 +0100	[thread overview]

Hi,

This is a newbie question about io_uring usage on Rocky 9.5 Kernel
5.14.0-503.22.1.e19_5.x86_64.

I want to use io_uring for UDP packet writing/reading to/from many
destinations/ports

If I understand the io_uring documentation correctly in the general case, if
I submit N different UDP write commands there is no guarantee they will
complete in the order submitted.
Is this true ?.

But, if I submit N * UDP write commands to the same file descriptor, ie same
destination and port, can I assume that they will complete in the order
submitted ?.

Thanks 

Michael
