Subject: Re: [PATCH v2 1/3] md: prevent adding disks with larger
 logical_block_size to active arrays


> When adding a disk to a md array, avoid updating the array's
> logical_block_size to match the new disk. This prevents accidental
> partition table loss that renders the array unusable.
>
> The later patch will introduce a way to configure the array's
> logical_block_size.
