Subject: Thank you for doc on Linux Kernel Module Programming Guide

Hello Peter,

Just wanted to thank you very much for your document on creating linux
kernel modules. ( http://www.tldp.org/LDP/lkmpg/2.6/html/x323.html )

You have no idea how helpful that doc was to me!

Thanks!!!!

PS. Minor errata. When I tested the code for hello-5.c I see that there is
       a mistake on how module_param_array is being used:

       module_param_array(myintArray, int, &arr_argc, 0000);

It seems to me that we should not pass in the address of arr_argc
but the arr_argc itself. The macro is already de-referencing it:

       module_param_array(myintArray, int, arr_argc, 0000);

Unrolled Macro produces:

    static struct kparam_array __param_arr_myintArray = {
       (sizeof(myintArray) / sizeof((myintArray)[0])),
       &arr_argc,     <======================== '&' put in by the macro!
       param_set_int,
       param_get_int,
       sizeof(myintArray[0]),
       myintArray };
