I read some FreeBSD kernel code, and it seems there is a standard
implementation of these calls that other vfs implementations use.
With the following patch, I get no more warnings, and coda seems to
work (but I only have used it 5 minutes since).

I don't understand how vobjects are used, or why they showed up
between 4.2 and 4.3.
