Stop exporting blk_rq_bio_prep
blk_rq_bio_prep is exported for use in exactly
one place. That place can benefit from using
the new blk_rq_append_bio instead.
So
- change dm-emc to call blk_rq_append_bio
- stop exporting blk_rq_bio_prep, and
- initialise rq_disk in blk_rq_bio_prep,
as dm-emc needs it.
