pr_host is a member of struct prison, which is a kernel structure.
It's under #ifdef _KERNEL, which is why you don't have a definition
for it. I'm not quite sure where you're getting your process list
from, but I think that p_prison is a kernel pointer in your context.
Obviously, trying to follow that from the userland won't do what you
want. :-)
Then again, I could be wrong. If you want, take the definition of
struct prison from /usr/include/sys/jail.h and paste it into your
code. That will get rid of the warning. If your program seg faults
when you try to run it, you'll know I was right.
