Subject: [RFC PATCH v2 2/7] create_syslog_header: Add durable name
Date: Wed, 13 May 2020 16:36:16 -0500 [thread overview]
Message-ID: <20200513213621.470411-3-tasleson@redhat.com> (raw)
In-Reply-To: <20200513213621.470411-1-tasleson@redhat.com>
This gets us a persistent durable name for code that logs messages in the
block layer that have the appropriate callbacks setup for durable name.
