Rik van Riel ebc2e5e6a4 ipc,sem: fix semctl(..., GETZCNT) ... The semctl GETZCNT returns the number of semops waiting for the specified semaphore to become zero. After commit 9f1bc2c902 ("ipc,sem: have only one list in struct sem_queue"), the semops waiting on just one semaphore are waiting on that semaphore's list. In order to return the correct count, we have to walk that list too, in addition to the sem_array's list for complex operations. This bug broke dbench; it works again with this patch applied.
