We have the block integrity code to support DIF/DIX in the the tree for

Given that we'll have a lot of work to do in this area with block
multiqueue I think it's time to either kill it off for good or make sure
we can actually use and test it.

Which would make an ideal topic for LSF, wouldn't it?

Personally, I doubt it's a good idea to kill it off, but
a proper (userland) API for it has been a long time missing.
