+function creates a vnode for a device of type
+.Fa type
+with a device number of
+.Fa dev ,
+and returns a pointer to it in
+.Fa vpp .
+.Pp
+Its arguments are:

+.It Fa dev
+The device number of the desired device.
+.It Fa vpp
+Where the vnode will be returned on success.
+.It Fa type
+The type of device, either:

+for a character device.
+.El
+.El
+.Pp
+.Fn bdevvp
+and
+.Fn cdevvp
+use getdevvp internally, specifying the third argument.
+.Fn bdevvp
+will create a vnode for a block device, and is used for the root filesystem
+and swap areas, among other things.
+.Fn cdevvp
+will create a vnode for a character device and is used in kernfs and in some
