First of all, as you are using Cent OS kernel, perhaps there is some
difference between your source code and mine, maybe kdbprivate.h is
not included correctly.
Second of all, I think you can remove the lines.
/* Any kdb commands that are not in the base code but are required
* earlier than normal initcall processing.
*/
call = & __kdb_initcall_start;
while (call < & __kdb_initcall_end) {
(*call)();
call++;
};
They are not existing in the latest kdb patches.
