As aio_context_t is treated by the kernel as a pointer, print it using printaddr. * aio.c (SYS_FUNC(io_setup)): Print the pointer to aio_context_t argument using printnum_ptr. (SYS_FUNC(io_destroy), SYS_FUNC(io_submit), SYS_FUNC(io_cancel), SYS_FUNC(io_getevents)): Print aio_context_t argument using printaddr. * tests/aio.c (sprint_aio_context_t): Remove. (main): Update expected output.
