DESCRIPTION
- vcount() is used to get the number of references to a par
- ticular device.
It allows for the fact that multiple vnodes may reference
- the same
device. count_dev() does the same thing as vcount(), but
- takes a dev_t
rather than a struct vnode pointer as an argument.
RETURN VALUES
- vcount() and count_dev() both return the number of refer
- ences to the
device.
