On a system that does not use an initramfs, /dev/root was always

This changes that processing so that "/dev/root" is only added to
/proc/mounts if a root device is not specified with the root= option on
the kernel command line.

Let me also point out that most of the time, the kernel actually has a
udev device name for an actual device...
I'm not sure what you mean. If you mean /dev/root is not an actual
device and should not be listed in /proc/mounts, that is correct and
that is why I am proposing this patch.
What I meant is that even if you *don't* specify a root= device the
modern kernel will generally have a usable name.
