Good catch. This RMID is useless unless we have got the existing
semaphore. According to SEMGET(2), seems should be:
semid = semget(semkey, 2, 0);
to obtain an existing semaphore?
Yes, I just wanted to avoid the purely
theoretical condition when someone
else removed this sem right before we
did second semget(). So I added IPC_CREAT
just as a safety measure.
Should I remove it?
Ping!
So how should I proceed with the patch?
Who can give reviewed-by?
