Convert the drm filesystem to the new internal mount API as the old
one will be obsoleted and removed. This allows greater flexibility in
communication of mount parameters between userspace, the VFS and the
filesystem.
See Documentation/filesystems/mount_api.txt for more information.

No clue about vfs, but feel free to merge through whatever tree this is
suitable for.

Hi Al,
I wonder if it would be possible to extend anon_inodes to return just an
anonymous inode, thereby allowing the drm filesystem to be removed in favour
of just using an anon_inode.
