Zap!

Fixed.

Done.


Jeff> Hmm, up until this point you use bi to mean bio_integrity, but

Err, uhm.  There is no bio_integrity.  There's the bio integrity
payload which I always refer to as struct bip *bip.  And struct
blk_integrity which is always bi.  I'm also anal about using bv for
the data bio_vec and iv for the integrity bio_vec.  I can't see any
place where I'm inconsistent.


Jeff> struct blk_integrity_exchg is not yet defined in your patch set,

bio-integrity.patch and blk-integrity.patch are artificially split up
to ease the review process.  They are not meant to be separate
changesets.

Nope.

Jeff> The above two loops look pretty much the same to me.  Can you

I've created helpers for marking head and tail of the ivec.
