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 };
