int
vcount( struct vnode *vp);
int
count_dev( struct cdev *dev);
DESCRIPTION
vcount() is used to get the number of references to a particular 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 struct cdev rather than a struct vnode pointer as an argument.RETURN VALUES
vcount() and count_dev() both return the number of references to the device.AUTHORS
