Subject: memory: Avoid an empty log message if there's nothing to log.
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=b9de4087685a16f3c8dd1a5b719219ff14ad5b65;p=sliver-openvswitch.git

memory: Avoid an empty log message if there's nothing to log.

I spotted this in a case where I ran ovsdb-server, by hand, on an empty
database.
