SubjectRe: [RFC V4 1/6] blk: prepare to make blk-rq-qos pluggable and modular

Yeah, that's what modularization does but why does it need a separate user
interface for loading? Everything else inits on insmod and exits on rmmod
and autoloading has been delegated to udev a very long time ago. The
interface you added for loading module doesn't make sense to me.

Thanks.
