__bio_clone_fast	__bio_clone_fast - clone a bio that shares the original bio's biovec@bio: destination bio@bio_src: bio to clone* Clone a &bio. Caller will own the returned bio, but not* the actual data it points to. Reference count of returned* bio will be one.
__bio_add_page	__bio_add_page - add page(s) to a bio in a new segment@bio: destination bio@page: start page to add@len: length of the data to add, may cross pages@off: offset of the data relative to @page, may cross pages
bio_iov_iter_get_pages	_iov_iter_get_pages - add user or kernel pages to a bio@bio: bio to add pages to@iter: iov iterator describing the region to be added* This takes either an iterator pointing to user memory, or one pointing to* kernel pages (BVEC iterator)
bio_copy_user_iov	_copy_user_iov - copy user data to bio@q: destination block queue@map_data: pointer to the rq_map_data holding pages (if necessary)@iter: iovec iterator@gfp_mask: memory allocation flags* Prepares and returns a bio for indirect user io, bouncing data
bio_map_user_iov	_map_user_iov - map user iovec into bio@q: the struct request_queue for the bio@iter: iovec iterator@gfp_mask: memory allocation flags Map the user space address into a bio suitable for io to a block* device. Returns an error pointer in case of error.
bio_split	_split - split a bio@bio: bio to split@sectors: number of sectors to split from the front of @bio@gfp: gfp mask@bs: bio set to allocate from* Allocates and returns a new bio which represents @sectors from the start of

__blk_queue_split	__blk_queue_split - split a bio and submit the second half@q: [in] request queue pointer@bio: [in, out] bio to be split@nr_segs: [out] number of segments in the first bio Split a bio into two bios, chain the two bios, submit the second half and
