Make sure that the offset and length arguments that we're using to construct WRITE SAME and DISCARD requests are actually aligned to the logical block size. Failure to do this causes other errors in other parts of the block layer or the SCSI layer because disks don't support partial logical block writes.
FYI, Bart has just been posting a patchset in that includes this, but goes further. Can you take a look at it?
