Automatic merge from submit-queue

Stop controller when the stop channel is closed (when queue is empty and Pop is hanging)

Fixes: #28158

When a ``Pop`` function is invoked over empty queue, the control loop inside the functions is stacked indefinitely. In order to break the loop, introduce logic that waits for a signal to exit the loop.

Intention of the PR is not to handle situation where manipulation operations are invoked over closed queue. Intention is to break the indefinite loop.
