> Several block device properties related to blocksize configuration must
> be in certain relationship WRT each other: physical block must be no
> smaller than logical block; min_io_size, opt_io_size, and
> discard_granularity must be a multiple of a logical block.
>
> To ensure these requirements are met, add corresponding consistency
> checks to blkconf_blocksizes, adjusting its signature to communicate
> possible error to the caller. Also remove the now redundant consistency
> checks from the specific devices.
