But why in /proc/partitions ?
Maybe /proc/partitions can go away eventually with all info available
under driverfs or so. But for the time being, /proc/partitions is used,
and some changes are planned to make identification of the devices
involved easier.
It is really ugly to stuff a lot of garbage into a file just because
it happens to exist already. If you want disk statistics, why not
put it in /proc/diskstatistics?
