Yeah, I was considering something along these lines.  Unfortunately you're
likely to only get 2 characters of the filesystem type if you used "sync"
for the rest.  This yields a potentially more effecient and safe
implementation:

char wchanbuf[7] = "  sync";
wchanbuf[0] = vp->v_type[0];
wchanbuf[1] = vp->v_type[1];

Looks good no?

Maybe I'll check that in.
