When I do io_uring coding, I just want to build my own kernel just once and debug/test fixes without the need to rebuild/reboot. For that I have some patches, see https://git.samba.org/?p=metze/linux/wip.git;a=shortlog;h=refs/heads/io_uring_livepatch.v6.1 I include them in the kernel I build and then I'm able to do quick adjustments until the feature I'm working on does what I want... metze
