How to get a kernel thread ID?

When we create a kernel thread using kthread_run(), how we can get the tid of the thread, is there something like pthread_self() or gettid() in kernel space?

In kernel-space, you don't need to ask something about thread like in userspace you do by calling gettid() -- you already have access to task_struct of your task:

struct task_struct* tsk = kthread_run(...);
pid_t tid = tsk->pid; // Thread id of newly created task (if it was successful)
