Subject: [PATCH v15 13/25] xfs: don't allow to enable DAX on fs-verity sealed inode
Date: Fri, 14 Aug 2026 11:24:30 +0200 [thread overview]
Message-ID: <20260814092448.1818082-14-aalbersh@kernel.org> (raw)
In-Reply-To: <20260814092448.1818082-1-aalbersh@kernel.org>
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.
