From f3dea7edd3d449fe7a6d402c1ce56a294b985261 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Sun, 10 Jun 2012 20:43:56 -0700 Subject: libceph: flush msgr queue during mon_client shutdown We need to flush the msgr workqueue during mon_client shutdown to ensure that any work affecting our embedded ceph_connection is finished so that we can be safely destroyed. Previously, we were flushing the work queue after osd_client shutdown and before mon_client shutdown to ensure that any osd connection refs to authorizers are flushed. Remove the redundant flush, and document in the comment that the mon_client flush is needed to cover that case as well.
