From 42ad631b4d0e0d6da0bfe375af99887251fbf970 Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Wed, 25 Aug 2021 21:45:44 +0800 Subject: [PATCH] ceph: don't WARN if we're force umounting Force umount will try to close the sessions by setting the session state to _CLOSING. We don't want to WARN in this situation, since it's expected.
