ceph: fix symbol versioning for ceph_monc_do_statfs (2016-07-28 15:32:53 +0200)
----------------------------------------------------------------
The highlights are:
* RADOS namespace support in libceph and CephFS (Zheng Yan and myself). The stopgaps added in 4.5 to deny access to inodes in namespaces are removed and CEPH_FEATURE_FS_FILE_LAYOUT_V2 feature bit is now fully supported.
* A large rework of the MDS cap flushing code (Zheng Yan).
* Handle some of ->d_revalidate() in RCU mode (Jeff Layton). We were overly pessimistic before, bailing at the first sight of LOOKUP_RCU.
On top of that we've got a few CephFS bug fixes, a couple of cleanups and Arnd's workaround for a weird genksyms issue.
