From b178cf4304f26551cb05915eb6c6b1736617366b Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Wed, 16 Aug 2017 17:27:05 +0800 Subject: [PATCH] ceph: don't use CEPH_OSD_FLAG_ORDERSNAP Inode can be moved between snap realms. It's possible inode is moved into a snap realm whose seq number is smaller than old snap realm's. So there is no guarantee that seq number inode's snap context always increases.
