I'm in total agreement with the patch (feel free to add my Acked-by:).
However, the minimum I/O size should still be reported correctly. We
don't allow min_io to be smaller than physical_block_size...
[root@10 ~]# grep . /sys/block/sdc/queue/{logical_block,physical_block,minimum_io}_size
/sys/block/sdc/queue/logical_block_size:512
/sys/block/sdc/queue/physical_block_size:4096
/sys/block/sdc/queue/minimum_io_size:4096
