FWIW, I was noticing in my kernel compile (RELENG_4 machine,
cvsup'ed yesterday) that there were numerous scope warnings about ucred.h
as well. I'll log a kernel build and send more details in a bit.
I only ran into this by accident. I'm setting up a file server and
did an install from a 4.1-R CD, then was playing around with my exports
file during make world/kernel install. If I'd waited to play with mountd
till after the reboot I wouldn't have seen the problem. Coincidentally, a
user got bit by this today too.
