 .Sh NAME
 .Nm insmntque ,
 .Nm insmntque1
 .Nd "associate a vnode with a mount"
 .Sh SYNOPSIS
 .In sys/param.h
 .In sys/vnode.h
 .Ft int
 .Fn insmntque "struct vnode *vp" "struct mount *mp"
 .Ft int
-.Fn insmntque1 "struct vnode *vp" "struct mount *mp" "void (*dtr)(struct vnode *, void *)" "void *dtr_arg"
+.Fn insmntque1 "struct vnode *vp" "struct mount *mp"
 .Sh DESCRIPTION
 The
 .Fn insmntque
 function associates a vnode with a mount.
 This includes updating
 .Va v_mount
 for the vnode, and inserting the vnode into the mount's vnode list.
 .Pp
-The mount reference count is incremented for each vnode added to the
+The indirect mount reference count, maintained as the count of the
+vnodes owned by it, is incremented for each vnode added to the
 mount, and that reference is decremented by
 .Xr vgone 9 .
 .Pp
 The mount's interlock is held while the vnode is inserted.
-For MP-safe file systems, the vnode must be exclusively locked.
+The vnode must be exclusively locked.
 .Pp
 On failure,
 .Fn insmntque
-calls
+resets vnode' operation vector to the vector of
+.Xr deadfs 9 ,
+clears
+.Va v_data ,
+and then calls
 .Xr vgone 9
-on the supplied vnode, and then drops the vnode lock and reference.
+and
+.Xr vput 9 .
 If more elaborated cleanup after
 .Fn insmntque
 failure is needed, the
 .Fn insmntque1
 function may be used instead.
-The
-.Fa dtr
-argument is a pointer to a function that is called on failure.
-This function may perform any custom cleanup.
-The vnode pointer is supplied as the first argument to
-.Fa dtr .
-The
-.Fa dtr_arg
-argument is the second, supplying any additional context needed.
+It does not do any cleanup following a failure, leaving all
+the work to the caller.
+In particular, the operation vector
+.Va v_op
+and
+.Va v_data
+fields of the vnode are kept intact.
 .Sh RETURN VALUES
 The
 .Fn insmntque
 function will always return 0, unless the file system is currently being unmounted
 in which case it may return
 .Dv EBUSY .
 Also,
 .Fn insmntque
 may be forced to insert the vnode into the mount's vnode list
 by setting the
 .Va VV_FORCEINSMQ
 flag in the vnode
 .Va v_flag ,
 even if the file system is being unmounted.
