[PATCH 00/10] RFC: move logical block size checking to the block core
This patch series aims to move the logical block size checking to the
block code.
This was inspired by missing check for valid logical block size in
virtio-blk which causes the kernel to crash in a weird way later on
when it is invalid.
I added blk_is_valid_logical_block_size which returns true iff the
block size is one of supported sizes.
I added this check to virtio-blk, and also converted
