    MD: add sync_super to mddev_t struct · 076f968b

    Add the 'sync_super' function pointer to MD array structure (struct mddev_s)
    
    If device-mapper (dm-raid.c) is to define its own on-disk superblock and be
    able to load it, there must still be a way for MD to initiate superblock
    updates.  The simplest way to make this happen is to provide a pointer in
    the MD array structure that can be set by device-mapper (or other module)
    with a function to do this.  If the function has been set, it will be used;
    otherwise, the method with be looked up via 'super_types' as usual.
