Looks like there are lots of work need to be done as well, for

Hmm ... loading a block driver, loading blk-iocost, unloading the block
driver and unloading blk-iocost works fine on my test setup.

- free the iocost structure after disabling it, otherwise iocost Module
can never be unloaded;

I will check whether struct ioc is freed when unloading blk-iocost.

Thanks,
