RTEMS | fix(posix): Prevent deadlock in aio_suspend (CID 1667285) (!954)

Thu Feb 5 15:57:37 UTC 2026

Kinsey Moore started a new discussion on cpukit/posix/src/aio_suspend.c: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/954#note_141697

 >          suspendcbp->requests_left++;
 >  
 >        } else {
 > +        pthread_mutex_unlock( &aio_request_queue.mutex );
 >          pthread_mutex_lock( &request->suspendcbp->mutex );

Is the locking order defined somewhere? Is it actually safe to release the queue lock before completion of this section?
