Subject: [Cluster-devel] [RESEND dlm/next 08/16] fs: dlm: allow lockspaces have zero lvblen
Date: Mon, 15 Aug 2022 15:43:20 -0400 [thread overview]
Message-ID: <20220815194328.2208580-9-aahringo@redhat.com> (raw)
In-Reply-To: <20220815194328.2208580-1-aahringo@redhat.com>
A dlm user can never use DLM_LKF_VALBLK flag with DLM API calls so a zero
lvblen should be allowed as per lockspace parameter.
