Scuze de raspunsul tarziu. Ai initializat primul argument al io_submit
(aio_context_t) folosind io_setup?

Din pagina de manual a io_setup[1]:
---
      io_setup() creates an asynchronous I/O context capable of receiving at least
       nr_events.  ctxp must not point to an AIO context that already exists, and
       must be initialized to 0 prior to the call.
