Emm, when I was preparing patches:
b681672752634a70ba1bd6b1c6b5ae2967ac13e5 ("Keep the definition of union
semun in one place")
586b51bf334b189d3e48760676ffeb39ce2a4371 ("sem_comm: pass a semun union
to semctl()")
I overlooked your patch. Sorry.
It seems the above patches fixes what you were trying to fix with your
patch, and so it became redundant.
Do you agree?
Sorry again.
