It's been a linux kernel coding standard to treat the sector size as
always 512 bytes which we have adopted - regardless of the actual
hardware underneath.

S and s, and B and b mean the same.

Both userspace and kernel code automatically respects alignment
constraints imposed by the devices underneath, such as larger sector sizes.
