    [PATCH] md: Use new single page bio splitting for raid0 and linear · a298fedc
    Neil Brown authored
    Sometimes raid0 and linear are required to take a single page bio that
    spans two devices.  We use bio_split to split such a bio into two.
    
    The the same time, bio.h is included by linux/raid/md.h so
    we don't included it elsewhere anymore.
    
    We also modify the mergeable_bvec functions to allow a bvec
    that doesn't fit if it is the first bvec to be added to
    the bio, and be careful never to return a negative length from a
    bvec_mergable funciton.
