| bio_clone_fast | _clone_fast - clone a bio that shares the original bio's biovec*@bio: bio to clone*@gfp_mask: allocation priority*@bs: bio_set to allocate from* Like __bio_clone_fast, only also allocates the returned bio |
| bio_uncopy_user | _uncopy_user - finish previously mapped bio*@bio: bio being terminated* Free pages allocated from bio_copy_user_iov() and write back data* to user space in case of a read. |
| 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_unmap_user | _unmap_user - unmap a bio*@bio: the bio being unmapped* Unmap a bio previously mapped by bio_map_user_iov(). Must be called from* process context.* bio_unmap_user() may sleep. |
| bio_map_kern_endio | |
| bio_map_kern | _map_kern - map kernel address into bio*@q: the struct request_queue for the bio*@data: pointer to buffer to map*@len: length in bytes*@gfp_mask: allocation flags for bio allocation* Map the kernel address into a bio suitable for io to a block* device |

| bio_copy_kern | _copy_kern - copy kernel address into bio*@q: the struct request_queue for the bio*@data: pointer to buffer to copy*@len: length in bytes*@gfp_mask: allocation flags for bio and page allocation*@reading: data direction is READ* copy the kernel address |
| bio_dirty_fn | _check_pages_dirty() will check that all the BIO's pages are still dirty.* If they are, then fine. If, however, some pages are clean then they must* have been written out during the direct-IO read. So we take another ref on |
| bio_check_pages_dirty | |
| blk_rq_unprep_clone | lk_rq_unprep_clone - Helper function to free all bios in a cloned request*@rq: the clone request to be cleaned up* Description:* Free all bios in @rq for a cloned request. |

| blkdev_issue_flush | lkdev_issue_flush - queue a flush*@bdev: blockdev to issue flush for*@gfp_mask: memory allocation flags (for bio_alloc)*@error_sector: error sector* Description:* Issue a flush for the block device in question |
| blk_rq_append_bio | Append a bio to a passthrough request. Only works if the bio can be merged* into the request based on the driver constraints. |
