Do what I did on Sparc wrt. TASK_SIZE, that way you won't need to include linux/sched.h The only reason you need linux/sched.h is to get test_tsk_thread_flag(), for your TASK_SIZE_OF(). But that's completely pointless for TASK_SIZE which only needs to look at the current thread's settings. Thus if you use test_thread_flag() for TASK_SIZE, instead of trying to borrow TASK_SIZE_OF()'s implementation, you'll no longer have this linux/sched.h dependency. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
