Hi all:2011/7/12 loody <miloody@xxxxxxxxx>Dear all:Is there faster way to find a give name of task?for example, I have a thread, named "test", is there faster way to get the task struct �by passing "test" to some kernel api?--
Regards,
I found a way as below:for_each_process(task) {
printk(�%s[%d]\n�, task->comm, task->pid);}But it is time-consuming to do so if I periodically want to know whether "test" exist or not.is there better way to do so?
If you have the thread pid you could find it really fast. By name i don't know any function that could help you with that.
You could search [1,2] for functions that could help you with that.�
If you are invoking from the thread you want, inside the kernel you can get the current variable that points to ther current process.
�[2]�struct task_struct *find_task_by_vpid(pid_t vnr);
Have a good work.
