Revision 97c85a828f36bbfffe9d77b977b65a5872b6cad4 authored by Yan, Zheng on 06 November 2014, 07:09:41 UTC, committed by Ilya Dryomov on 17 December 2014, 17:09:51 UTC
Current snaphost code does not properly handle moving inode from one empty snap realm to another empty snap realm. After changing inode's snap realm, some dirty pages' snap context can be not equal to inode's i_head_snap. This can trigger BUG() in ceph_put_wrbuffer_cap_refs() The fix is introduce a global empty snap context for all empty snap realm. This avoids triggering the BUG() for filesystem with no snapshot.
