/*
    C header file for debugging print
    DEBUG_HEADER can be modified
    and also the if you need debugging in kernel
    you may need define PRINT as printk or other print funcs.

    Usage:
    Compile with gcc and options like `-D DEBUG_MODE` will enable the debug print
    if no `-D DEBUG_MODE` will not make the debug function work bug defined.
