       modules. The output buffer
        format is adjacent null-terminated strings; ret is set to the number
       of mod ules.

       QM_REFS        Returns the names of all modules using the indicated
       module.  This is the inverse of QM_DEPS. The output buffer format is
       adjacent null-te rminated strings; ret is set to the number of modules.

       QM_SYMBOLS        Returns the symbols and values exported by the kernel
       or t he indicated module. The buffer format is an array of:
                      struct module_symbol
                     {
                       unsigned long value;
                       unsigned long name;
                     };
                     followed by null-terminated strings. The value of name is
       the character offset of the string relative to the start of buf; ret is
       set to t he number of symbols.

           {
             unsigned long value;
             unsigned long value;
           } QM_INFO        Returns miscelaneous information about the
       indicated module.  The output buffer format is:
                     struct module_info
                     {
                       unsigned long address;

                       unsigned long flags;
                     };
                     where address is the kernel address at which the module
       reside s, size is the size of the module in bytes, and flags is a mask
       of MOD_RUNNI NG, MOD_AUTOCLEAN, et al that indicates the current status
       of the module. re t is set to the size of the            module_info
       struct.
