I suspect the whole series could use some reordering. patch 1: add ->bio_split and blk_queue_split patch 2..n: one for each non-trivial driver that implements ->merge_bvec_fn to remove it and instead split bios in ->make_request. The md patch to do the right thing in chunk_aligned_read goes into the general md patch here. The bcache patch also goes into this series. patch n+1: - add blk_queue_split calls for remaining trivial drivers patch n+2: - remove ->merge_bvec_fn and checking of max_sectors a for all drivers, simplify bio_add_page patch n+2: - remove splitting in blkdev_issue_discard patch n+3 - remove bio_fits_rdev patch n+4 - remove bio_get_nr_vecs patch n+4 - use bio_add_page patch n+5 - update documentation -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
