33.Nm vgone , vgonel
34.Nd "prepare a vnode for reuse"
35.Sh SYNOPSIS
36.In sys/param.h
37.In sys/vnode.h
38.Ft void
39.Fn vgone "struct vnode *vp"
40.Ft void
41.Fn vgonel "struct vnode *vp" "struct thread *td"
42.Sh DESCRIPTION
43.Fn vgone
44and
45.Fn vgonel
46prepare a vnode for reuse by another file system.
47The preparation includes the cleaning of all file system specific data and
48the removal from its mount point vnode list.
49.Pp
50If the vnode has a
51.Va v_usecount
52of zero, and its
53.Dv VI_DOOMED
54flag is not set, it is moved to the head of the free list
55as in most cases the vnode
56is about to be reused, or its file system being unmounted.
57.Pp
58The difference between
59.Fn vgone
60and
61.Fn vgonel
62is that
63.Fn vgone
64locks the vnode interlock and then calls
65.Fn vgonel
66while
67.Fn vgonel
68expects the interlock to already be locked.
