[PATCH] remove compat code for old devfs naming scheme

[Christoph Hellwig <hch@infradead.org>]

Hi Richard,

current init/do_mounts.c contains the devfs_make_root/convert_name
functions which provide compatiblility for the old, pre kernel-merge
devfs naming scheme in the root= kernel command line.

As this was never present in official kernels there is really no need
in keeping it - it just bloats the kernel.

Could you please forward this patch to Linus and maybe Marcelo with
your next devfs update?

	Christoph
