From 3b5ede07b55b52c3be27749d183d87257d032065 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Fri, 20 Jul 2012 15:22:53 -0700 Subject: [PATCH] libceph: fix fault locking; close socket on lossy fault If we fault on a lossy connection, we should still close the socket immediately, and do so under the con mutex. We should also take the con mutex before printing out the state bits in the debug output.
