Kernel uses DEV_BSIZE devices and needs a proper translations function.
Userland uses device block sizes and needs a proper translation function.
Only the translation function (==fsbtodb()) needs to be implemented
differently because of the different environment. Other parts of the code,
shared by kernel and userland, simply use this abstraction.
This is not about redesigning the driver API and only marginally about
cleaning up old code.
