1. How to get id of a schedulable entity in kernel space i.e. pthread_create is done in user space, is task_struct->pid the thread of this newly created thread? Does this pid represent a thread and task_struct->tgid the leader of the thread group i.e. main thread? 2. If all answers to 1 are positive then is task_struct->pid eqal to output of sys_gettid()? 3. Why the hell sys_gettid is imlemented in timer.c? -Leo. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
