Hi Geert,

BTW, there was also "[PATCH] [WIP] selftests/seccomp: Add m68k support"
https://lore.kernel.org/linux-m68k/alpine.DEB.2.21.2008261315050.25325@xxxxxxxxxxxxxx/

I kept on up-porting it, but haven't exercised it recently.

See attached for test results on my ARAnyM image (Laurent's qemu image, essentially).

Is that any different from what you got in your earlier tests?

Cheers,
