Hi, all:
Here is a snippet of linux-v3.4 which drives me crazy.
Because init_task hasn't been declared yet when init_thread_union is
initializing. Why is there no compiling error? Any hint would be helpful.
union thread_union init_thread_union __init_task_data =
{ INIT_THREAD_INFO(init_task) };
/*
* Initial task structure.
*
* All other task structs will be allocated on slabs in fork.c
*/
struct task_struct init_task = INIT_TASK(init_task);
