Subject: [PATCH 2/2 net-next] libceph: Use __counted_by() in struct ceph_snap_context
Date: Sun, 19 May 2024 11:09:59 +0200 [thread overview]
Message-ID: <c883cccd53beb412f4806d28f48e8a3ddd4f0995.1716109606.git.christophe.jaillet@wanadoo.fr> (raw)
In-Reply-To: <5b7c72bdb52703bbfa5511ed500aed4babde1308.1716109606.git.christophe.jaillet@wanadoo.fr>
Annotate the 'snaps' flexible array in "struct ceph_snap_context" with
__counted_by() so that additional checks can be made, if enabled.
