Hi,

I did similar work 6 months ago but I don't have the time to work on it
anymore.
The patches are at:
http://bsd.miki.eu.org/~antoine/quota/quota-simple.diff and
http://bsd.miki.eu.org/~antoine/quota/quota-full.diff
IIRC I used an sx lock because you can fault and sleep while
copyin/copyout

Cheers,

Antoine
