From ec87ef4309d33bd9c87a53bb5152a86ae7a65f25 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 31 May 2012 20:27:50 -0700 Subject: [PATCH] libceph: drop connection refcounting for mon_client All references to the embedded ceph_connection come from the msgr workqueue, which is drained prior to mon_client destruction. That means we can ignore con refcounting entirely.
