Subject: [RFC 9/9] __xfs_printk: Add durable name to output
Date: Mon, 23 Dec 2019 16:55:58 -0600 [thread overview]
Message-ID: <20191223225558.19242-10-tasleson@redhat.com> (raw)
In-Reply-To: <20191223225558.19242-1-tasleson@redhat.com>
Add persistent durable name to xfs messages so we can
correlate them with other messages for the same block
device.
