My last concern is whether off_t is correct there, or it should be
vm_ooffset_t.  I.e., should the size argument represent a file size
or VM object size?  As a matter of fact, the size argument is
transformed into vm_ooffset_t inside vnode_create_vobject(), so we
can safely decide that vnode_create_vobject() is on the vnode side
of the vnode-VM interface.  Thanks!
