Try to cancel the pending aio seems useless, how about waiting aios until
completed?
Can you test like below?
for (i = 0; i < NAIOCB; i++) {
do {
usleep(10000);
ret = aio_error(&aiocb[i]);
} while (ret == EINPROGRESS);
if (ret < 0) {
printf(TNAME " Error at aio_error() : %s\n",
strerror(ret));
exit(PTS_FAIL);
}
}
Thanks,
