Oh, my bad. I thought Minix (the OS) had some licensing incompatibilities
with Linux, and this repo takes code from Minix. But that may be long in
the past.

Would an in-tree but out of kernel implementation be an idea? Like how
kselftest is integrated in the code, even though most of that also takes
place in userland. That would guarantee a level of support, at least for
the time being. I could take the code, verify it, and write some tests
for in selftest.

And there is still the issue of what we do for the syzbot bugs until a
more permanent solution is achieved.

Anyway, this probably goes over my head as a clueless beginner. Just
trying to see where I can help. Thanks a lot Jeff for you answers, I
appreciate it.

Jori.
