Re: [dm-devel] [PATCH v6 12/13] block: Add bio_clone_bioset(), bio_clone_kmalloc()

Previously, there was bio_clone() but it only allocated from the fs bio

__bio_clone().

This changes bio_clone() to become bio_clone_bioset(), and then we add
bio_clone() and bio_clone_kmalloc() as wrappers around it, making use of
the functionality the last patch adedd.

This will also help in a later patch changing how bio cloning works.
