VPUT(9)

NAME
vput - Decrement the primary reference count for a vnode and unlock it

SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
void
vput(struct vnode *vp);

DESCRIPTION
Decrement the vnode's primary reference count (via the v_sysref field) and unlock the vnode.

vp  The vnode in question.

This operation is functionally equivalent to calling vn_unlock(9) followed by vrele(9). Releasing the last primary reference on a vnode will cause it to be deactivated and either moved to the free list or cached. Vnodes with namecache and/or VM objects are typically marked as being cached unless the system needs the memory for other purposes.
