Subject: [PATCH 20/20] mkfs.xfs: add verity parameter
Date: Sun, 17 Mar 2024 09:39:02 -0700	[thread overview]
Message-ID: <171069247951.2685643.5838885180227203125.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <171069247657.2685643.11583844772215446491.stgit@frogsfrogsfrogs>

From: Andrey Albershteyn <aalbersh@redhat.com>

fs-verity brings on-disk changes (inode flag). Add parameter to
enable (default disabled) fs-verity flag in superblock. This will
make newly create filesystem read-only for older kernels.
