As I indicated already in this discussion, dm started to use
merge_bvec_fn as a cheap way of avoiding splitting and this improved
overall efficiency. Often it's better to pay the small price of calling
that function to ensure the bio is created the right size in the first
place so it won't have

Reusing bios is something that's been highly frowned upon in the past,
but driver code keeps doing it anyways. If it's going to happen anyways,
we should provide a generic method.
This'll help with getting rid of bi_destructor - drivers/block/pktcdvd.c
was open coding it, by doing a bio_init()
