dasd_cmd just implements three ioctls which are wrappers around functionality in the core kernel or other modules. When merging those into dasd_mod they just add 22 lines of code which is far less than the amount of code removed in the last two patches, and which doesn't spill into another 4k pages when build modular, while removing a 128lines module.
