Thank you for confirming that.
Do you know how your test program is using io_uring?
I have been trying to put the pieces together on what io_uring is doing that stops the coredump. The fact that it takes a little while before it kills the coredump is a little puzzling. The code looks like all of the io_uring operations should have been canceled before the coredump starts.
Thanks, Eric
