Hello,
there's a minor error in the semctl(2) man page, the correct data type
for SEM_STAT_ANY return buffer is "struct semid_ds" because the kernel
code path is the same as for IPC_STAT and SEM_STAT:
https://github.com/torvalds/linux/blob/5ee88057889bbca5f5bb96031b62b3756b33e164/ipc/sem.c#L1789
The man page currently says that the data type for IPC_STAT and SEM_STAT
is "struct semid_ds" (correct) but then it says the data type for
SEM_STAT_ANY is "struct seminfo" (wrong).

Hello Martin,
This was fixed a few days ago.
