VOP_INACTIVE(9)	       FreeBSD Kernel Developer's Manual       VOP_INACTIVE(9)

NAME
     VOP_INACTIVE, VOP_RECLAIM -- reclaim file system resources	for a vnode

SYNOPSIS
     #include <sys/param.h>
     #include <sys/vnode.h>

     int
     VOP_INACTIVE(struct vnode *vp, struct thread *td);

     int
     VOP_RECLAIM(struct	vnode *vp, struct thread *td);

DESCRIPTION
     The arguments are:

     vp	 The vnode being reclaimed.

     VOP_INACTIVE() is usually called when the kernel is no longer using the
     vnode.  However, there is no guarantee that it will be called at all, for
     example if	the last reference was dropped while the vnode lock could not
     be	upgraded to exclusive without sleeping.	 This may be because the ref-
     erence count reaches zero or it may be that the file system is being
     forcibly unmounted	while there are	open files.  It	can be used to reclaim
     space on the last close of	an `open but deleted' file.

     VOP_RECLAIM() is called when a vnode is being reused for a	different file
     system.  Any file system specific resources associated with the vnode
     should be freed.

LOCKS
     For both VOP_INACTIVE() and VOP_RECLAIM(),	the vp will be exclusively
     locked on entry, and must be left exclusively locked on return.
