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 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 file system is being forcibly unmounted while there are open
     files.  It can be used to reclaim space for ‘open but deleted’ files.

     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.
