From b3d1dbbdd5670d8a9fb01f7dfb1cac522ff6795a Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Mon, 14 Dec 2009 14:58:11 -0800 Subject: [PATCH] ceph: don't save sent messages on lossy connections For lossy connections we drop all state on socket errors, so there is no reason to keep sent ceph_msg's around.
