VOP_INACTIVE(9)

NAME
VOP_INACTIVE, VOP_RECLAIM - reclaim filesystem resources for a vnode

SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
int
VOP_INACTIVE(struct vnode *vp, struct proc *p);
int
VOP_RECLAIM(struct vnode *vp, struct proc *p);

DESCRIPTION

The arguments are:

vp  the vnode being reclaimed

VOP_INACTIVE(9) is called when the kernel is no longer using the vnode. This may be because the reference count reaches zero or it may be that the filesystem is being forcibly unmounted while there are open files. It can be used to reclaim space for 'open but deleted' files. VOP_RECLAIM(9) is called when a vnode is being reused for a different filesystem. Any filesystem specific resources associated with the vnode should be freed.

PSEUDOCODE

    int
    vop_inactive(struct vnode *vp)
    {
        if (link count of vp == 0) {
    	/*
    	 * Reclaim space in filesystem for vp.
    	 */
    	...;
        }
        return 0;
    }
    int
    vop_reclaim(struct vnode *vp)
    {
        /*
         * Clean out the name cache.
         */
        cache_purge(vp);
        /*
         * Free filesystem-related data.
         */
        ...;
        return 0;
    }
