The current described behaviour of rte_ctrl_thread_create is rigid
which makes the implementation of the function complex.
The behavior is abstracted to allow for simplified implementation.

Have you considered using a POSIX condition variable instead of atomics for
synchronization?

No, I have not considered. The current implementation is complex because of the error handling of pthread_barrier_xxx APIs. I am thinking similar complexity will come in with the condition variable functions.

I am using atomic variable in this patch to synchronize which does not need much error handling which simplifies the implementation.
