Subject: [PATCH v3 20/28] xfs: add fs-verity ro-compat flag
Date: Fri, 6 Oct 2023 20:49:14 +0200 [thread overview]
Message-ID: <20231006184922.252188-21-aalbersh@redhat.com> (raw)
In-Reply-To: <20231006184922.252188-1-aalbersh@redhat.com>
To mark inodes sealed with fs-verity the new XFS_DIFLAG2_VERITY flag
will be added in further patch. This requires ro-compat flag to let
older kernels know that fs with fs-verity can not be modified.
Signed-off-by: Andrey Albershteyn <aalbersh@redhat.com>
