    block: add bsg helper library · aa387cc8
    Mike Christie authored
    This moves the FC classes bsg code to the block layer and
    makes it a lib so that other classes like iscsi and SAS can use it.
    
    It is helpful because working with the request queue, bios,
    creating scatterlists, etc are a pain that the LLD does not
    have to worry about with normal IOs and should not have to
    worry about for bsg requests.
