On that argument, we'll eliminate almost all Fibre Channel devices!

I think the qualification for appearing in driverfs is actually possessing a
driver. Therefore, we accept FC and iSCSI. Things which appear as
FileSystems are debatable, but not anything which has a real device driver.

Perhaps it's more a question of whether power management belongs as an every
unit item in driverfs. As you say, we get problems where the device is shared
between multiple computers.
