The do_exit() function in kernel/exit.c is responsible for general cleanup on a process [1]. Whether a process dies gracefully or abruptly, the kernel calls do_exit() to clean up all the resources owned by the process, like opened files or acquired locks. I would imagine the io_uring related stuff is cleaned up there as well.

Yes, it does clean up io_uring related files.
