    Sorry I didn't see this email earlier.

    Probably due to this:

    #ifdef CONFIG_LBD
    typedef u64 sector_t;
    typedef u64 blkcnt_t;
    typedef unsigned long sector_t;
    typedef unsigned long blkcnt_t;

    With a 64-bit machine, your sector_t and blkcnt_t are already 64 bits
    wide, so CONFIG_LBD is not required.
