This is far too short, please see the notes below on trying
to make this more informative.

I belive last time this was brought up I asked about the affect
this has on the userspace. The following issues would be helpful
or essential to have noted in the header about the effect of this.

- Does it change the /dev name of the device? if so I would thinl
  carefully about applying it, as it would be a change in the way
  that userspace sees the kernel.

- Does it change the kernel output itself? A note on what diffeences
  can be seen in things like dmesg would be helpful.

- Are there any other side effects

- Why is this a bug? Maybe the previous points will explain what is
  going on, but if not, then a reasonably concise description of
  what is going on here.
