Subject: [PATCH] semctl.2: Correct SEM_STAT_ANY description
Date: Tue, 29 Dec 2020 12:03:11 +0100	[thread overview]
Message-ID: <20201229110309.7774-1-alx.manpages@gmail.com> (raw)

From: Yang Xu <xuyang2018.jy@cn.fujitsu.com>

Since kernel commit a280d6dc77eb
("ipc/sem: introduce semctl(SEM_STAT_ANY)"),
it only skips read access check when using SEM_STAT_ANY command.
And it should use the semid_ds struct instead of seminfo struct.
Fix this.
