There was recent commit[1] to rename the "thread_info" member of the
task_struct to "stack":
- struct thread_info *thread_info;
+ void *stack;
To resolve it we simply need to change the hardcoded value for the offset
lookup in task.c:
--- task.c.ori 2007-05-24 09:54:43.000000000 -0600
+++ task.c 2007-05-24 10:41:50.000000000 -0600

MEMBER_OFFSET_INIT(task_struct_thread_info, "task_struct",

if (VALID_MEMBER(task_struct_thread_info)) {
MEMBER_OFFSET_INIT(thread_info_task, "thread_info", "task");
MEMBER_OFFSET_INIT(thread_info_cpu, "thread_info", "cpu");
However, I'm not sure what the best way to keep backwards compatibility for
kernels < 2.6.22.

This should suffice:
< MEMBER_OFFSET_INIT(task_struct_thread_info, "task_struct",
< "thread_info");

Thanks for nipping this one in the bud,
