Any code in the system which obtains a primary reference to a vnode via
.Xr vref 9
typically releases that reference with
.Fn vrele
when it is finished with the vnode.
Upon release of the last primary
reference, the vnode will be deactivated and either moved to the free
list for later reuse or marked as being cache.
The vnode can be reactivated at any time prior to the system reusing it.
