NAME

vgone, vgonel - prepare a vnode for reuse

SYNOPSIS

#include <sys/param.h>
#include <sys/vnode.h>
void
vgone(struct vnode *vp);
void
vgonel(struct vnode *vp, struct thread *td);

DESCRIPTION

vgone() and vgonel() prepare a vnode for reuse by another

file system.
The preparation includes the cleaning of all file system

specific data
and the removal from its mount point vnode list.

If the vnode has a v_usecount of zero, and its VDOOMED flag

is not set,
it is moved to the head of the free list as in most cases

the vnode is
about to be reused, or its file system being unmounted.

The difference between vgone() and vgonel() is that vgone()

locks the
vnode interlock and then calls vgonel() while vgonel() ex

pects the interlock to already be locked.
