From 177a97d5c55ee6a2d5dcd3cf0893546190b10f7a Mon Sep 17 00:00:00 2001 From: John Spray Date: Wed, 8 Mar 2017 12:13:46 +0000 Subject: [PATCH] mds: shut down finisher before objecter Some of the finisher contexts would try to call into Objecter. We mostly are protected from this by mds_lock+the stopping flag, but at the Filer level there's no mds_lock, so in the case of file size probing we have a problem.
