In addition to the exofs and osd removal I sent out I've also done the
SCSI cleanup here:

http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/remove-scsi-osd

unfortunately the bsg-lib code also uses the block bidi support, but
then again at least for the blk-mq case that code isn't too bad,
and Jens is about to remove the legacy request code.
