Are you certain you shouldn't at least be exposing a different
logical_block_size to upper layers?

To be honest, I tested my patches in QEMU with 4k Logical block size and on
a device with 4k LBA size.

I did a quick test with 512B LBA size in QEMU, and I didn't see any
failures when I ran my normal test suite.

Do you see any problem with exposing the same LBA as the underlying device?

Do you see any issues here? If not, I can send the next version with the
other two changes you suggested.

Thanks,
Pankaj
