    Subject[PATCH v4 00/24] Prep work for immutable bio vecs
    Date
    Since last time - split bio integrity stuff out into its own 2 patch series.

    Also changed bio_advance() a bit - it now explicitly special cases discard and
    WRITE_SAME requests, so that partial completions will work. Previously, partial
    completions worked for other requests but would've silently blown up for those
    - this'll be of use later too, for generic bio splitting.

    I've got 3 patch series queued up but they all should be independent - git tree
    is at

    http://evilpiepirate.org/git/linux-bcache.git for-jens

    It's on top of jens' for-next branch.


    Kent Overstreet (24):
    block: Add bio_advance()
    block: Refactor blk_update_request()
    md: Convert md_trim_bio() to use bio_advance()

    raid5: use bio_reset()
    raid1: Refactor narrow_write_error() to not use bi_idx
    block: Add bio_copy_data()
    pktcdvd: use bio_copy_data()
    pktcdvd: Use bio_reset() in disabled code to kill bi_idx usage
    raid1: use bio_copy_data()
    bounce: Refactor __blk_queue_bounce to not use bi_io_vec
    block: Add bio_for_each_segment_all()
    block: Convert some code to bio_for_each_segment_all()
