Thread-topic: blkfront/back and sector size of 2048 with CDROM's
It looks like mounting a physical CDROM under the windows gpl pv drivers
doesn't work, and I suspect that the problem is because the CDROM uses a
sector size of 2048 instead of 512.

Do the pages passed between the front and backend scale to using
different sector sizes, or do I have to do some magic to fudge them back
to 512?

Thanks

James
