Yeah, I remember now why I didn't want this.
It means that by default if somebody installs an old kernel from the
time when 4.1/4.2 support was much more experimental, then they get
4.1 and 4.2 by default.
Whereas if rpc.nfsd just doesn't touch those values then they'll get the
kernel default, leaving 4.1/4.2 off on older kernels and turning them
back on on newer kernels.
But, whatever, I'm not sure that was the right approach. And 4.2's been
the kernel's default for 3 years now anyway.
So, ACK to the patch, thanks.
