    tracing: Revert "tracing: Remove pid in task_rename tracing output"

    This reverts commit e3f6a42272e028c46695acc83fc7d7c42f2750ad.

    The commit says that the tracepoint only deals with the current task,
    however the following case is not current task:

    comm_write() {
        p = get_proc_task(inode);
        if (!p)
            return -ESRCH;

        if (same_thread_group(current, p))
            set_task_comm(p, buffer);
    }
    where set_task_comm() calls __set_task_comm() which records
    the update of p and not current.

    So revert the patch to show pid.
