From e2663ab60de59d20fa33da3528f6d5359f8eb003 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 16 Feb 2010 22:01:03 -0800 Subject: [PATCH] ceph: allow connection to be reopened by fault callback Fix the messenger to allow a ceph_con_open() during the fault callback. Previously the work wasn't getting queued on the connection because the fault path avoids requeued work (normally spurious). Loop on reopening by checking for the OPENING state bit. This fixes OSD reconnects when a TCP connection drops.
