Merge branch 'wireguard-patches-for-5-18-rc6'
Jason A. Donenfeld says:
====================
wireguard patches for 5.18-rc6
In working on some other problems, I wound up leaning on the WireGuard
CI more than usual and uncovered a few small issues with reliability.
These are fairly low key changes, since they don't impact kernel code
itself.
One change does stick out in particular, though, which is the "make
routing loop test non-fatal" commit. I'm not thrilled about doing this,
but currently [1] remains unsolved, and I'm still working on a real
solution to that (hopefully for 5.19 or 5.20 if I can come up with a
good idea...), so for now that test just prints a big red warning
instead.
