From 700b0d2a2db3b8c30a23d40335e438030c56a968 Mon Sep 17 00:00:00 2001 From: Erik Skultety Date: Tue, 14 Nov 2017 14:32:16 +0100 Subject: [PATCH] daemon: virtlogd: Drop the server shortcut ref pointer We put the server into a hash table as we do with the other daemons, there is no compelling reason why it should have another pointer dedicated just to the server. Besides, the locking daemon doesn't have it and virtlogd is essentially a copy paste of virtlockd.
