Subject: [PATCH v3 22/28] xfs: initialize fs-verity on file open and cleanup on inode destruction
Date: Fri, 6 Oct 2023 20:49:16 +0200 [thread overview]
Message-ID: <20231006184922.252188-23-aalbersh@redhat.com> (raw)
In-Reply-To: <20231006184922.252188-1-aalbersh@redhat.com>
fs-verity will read and attach metadata (not the tree itself) from
a disk for those inodes which already have fs-verity enabled.
