vrele
— decrement
the use count for a vnode
#include
<sys/param.h>
#include <sys/vnode.h>
int
vrele
(struct
vnode *vp);
Decrement the v_usecount field of the vnode specified by vp.
Any code in the system which uses a vnode should call
vrele
() when
it is finished with the vnode. If the v_usecount field
of the vnode reaches zero, the vnode will be placed on the free list.
vrele
() returns 0 if it can guarantee that
it did not sleep.
