This patch series aims to move the logical block size checking to the=0D
block code.=0D
=0D
This was inspired by missing check for valid logical block size in=0D
virtio-blk which causes the kernel to crash in a weird way later on=0D
when it is invalid.=0D
=0D
I added blk_is_valid_logical_block_size which returns true iff the=0D
block size is one of supported sizes.=0D
=0D
I added this check to virtio-blk, and also converted  few block drivers=0D
that I am familiar with to use this interface instead of their=0D
own implementation.=0D
=0D
Best regards,=0D
