Subject: [PATCH v5 19/24] xfs: don't allow to enable DAX on fs-verity sealsed inode
Date: Mon, 4 Mar 2024 20:10:42 +0100 [thread overview]
Message-ID: <20240304191046.157464-21-aalbersh@redhat.com> (raw)
In-Reply-To: <20240304191046.157464-2-aalbersh@redhat.com>
fs-verity doesn't support DAX. Forbid filesystem to enable DAX on
inodes which already have fs-verity enabled. The opposite is checked
when fs-verity is enabled, it won't be enabled if DAX is.
