    block: Change bio_split() to respect the current value of bi_idx · 5b83636a
    Kent Overstreet authored
    In the current code bio_split() won't be seeing partially completed bios
    so this doesn't change any behaviour, but this makes the code a bit
    clearer as to what bio_split() actually requires.
    The immediate purpose of the patch is removing unnecessary bi_idx
    references, but the end goal is to allow partial completed bios to be
    submitted, which along with immutable biovecs enables effecient bio
    Some of the callers were (double) checking that bios could be split, so
    update their checks too.
