Do you happen to know if there is userspace that will run in qemu-system-m68k that can be used for testing?I surmise so. I don't use qemu myself - either ARAnyM, or actual hardware. Hardware is limited to 14 MB RAM, which has prevented me from using more than simple regression testing. In particular, I can't test sys_io_uring_setup there. Adrian uses qemu a lot, and has supplied disk images to work from on occasion. Maybe he's got something recent enough to support sys_io_uring_setup ... I've CC:ed him in, as I'd love to do some more testing as well.
As well as Debian/m68k, there is also a Gentoo/m68k stage3 rootfs available here: https://sourceforge.net/projects/linux-mac68k/files/Gentoo%20m68k%20unauthorized/ I built that rootfs last year using Catalyst. Some background (including the qemu-system-m68k command-line) can be found here: https://forums.gentoo.org/viewtopic-t-1100780.html
