From: Rob Gardner <rob.gardner@xxxxxxxxxx> [ Upstream commit 53eb2516972b8c4628651dfcb926cb9ef8b2864a ] A bug was reported that the semtimedop() system call was always failing eith ENOSYS. Since SEMCTL is defined as 3, and SEMTIMEDOP is defined as 4, the comparison "call <= SEMCTL" will always prevent SEMTIMEDOP from getting through to the semaphore ops switch statement. This is corrected by changing the comparison to "call <= SEMTIMEDOP". Orabug: 20633375 Signed-off-by: Rob Gardner <rob.gardner@xxxxxxxxxx> Signed-off-by: David S.
