My idea was that the patch in its current form would be less
controversial if it can't break anything, but you're certainly
right that the description doesn't match what the patch does.

I'm now integrating the half of patch 5, as you suggested.
I would much appreciate if you could verify my assumptions
about the blkdev_get/blkdev_put functions in the combined patch.
