Well, Hilf had it go through the syzbot testing, and Jiri seems to
have tested it on his setup too, so it looks like it's all good, and
you can change the "Not-Yet-Signed-off-by" to be a proper sign-off
from me.

It would be good to have some UML testing done, but at the same time I
do think that anybody running UML on modern kernels should be running
a modern user-mode setup too, so while the exact SIGSEGV details may
have been an issue in 2011, I don't think it's reasonable to think
that it's an issue in 2024.
