    Commit 79bd9959 ("blk: improve order of bio handling in generic_make_request()")
    changed current->bio_list so that it did not contain *all* of the
    queued bios, but only those submitted by the currently running
    make_request_fn.
    
    There are two places which walk the list and requeue selected bios,
    and others that check if the list is empty.  These are no longer
    correct.
    
    So redefine current->bio_list to point to an array of two lists, which
    contain all queued bios, and adjust various code to test or walk both
    lists.
