Subject: [PATCH] xfs: Use consistent logging message prefixes
Date: Wed, 08 Jul 2015 11:15:12 -0700 [thread overview]
Message-ID: <1436379312.2682.90.camel@perches.com> (raw)
The second and subsequent lines of multi-line logging messages
are not prefixed with the same information as the first line.
Separate messages with newlines into multiple calls to ensure
consistent prefixing and allow easier grep use.
