I had a strange problem of core file getting truncated. I could not find any stack trace. So, i wrote a kernel module. Which will find a task_struct using pid. find_task_jby_pid. then i used show_stack for the same task struct to list out the stack trace. But it is printing the kernel stack not user stack. Any idea how to print user stack . -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
