Basically speaking the raid code can't access the bvec table directly like referencing .bi_vcnt or .bi_io_vec once multipage bvec is supported, especially after pages are added to the bio via bio_add_page(). I am looking at the raid1 code, and maybe we can discuss a bit about the cleanup. > And > will dm code involved in as well ? No, nothing at all, and no such usage in dm code.
