Out of curiosity, do you have any idea whether there is any storage that
offers DIF with a different Logical Block Size than 512 (I haven't see
any, although, that doesn't say much)? Just re-read some parts of our
HBA specs and we probably would be in trouble, if it does, with how we do
things here.
