Merge tag 'ceph-for-4.8-rc1' of git://github.com/ceph/ceph-client
Pull Ceph updates from Ilya Dryomov: "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" * tag 'ceph-for-4.8-rc1' of git://github.com/ceph/ceph-client: (34 commits) ceph: fix symbol versioning for ceph_monc_do_statfs ceph: Correctly return NXIO errors from ceph_llseek ceph: Mark the file cache as unreclaimable ceph: optimize cap flush waiting ceph: cleanup ceph_flush_snaps() ceph: kick cap flushes before sending other cap message ceph: introduce an inode flag to indicates if snapflush is needed ceph: avoid sending duplicated cap flush message ceph: unify cap flush and snapcap flush ceph: use list instead of rbtree to track cap flushes ceph: update types of some local varibles ceph: include 'follows' of pending snapflush in cap reconnect message ceph: update cap reconnect message to version 3 ceph: mount non-default filesystem by name libceph: fsmap.user subscription support ceph: handle LOOKUP_RCU in ceph_d_revalidate ceph: allow dentry_lease_is_valid to work under RCU walk ceph: clear d_fsinfo pointer under d_lock ceph: remove ceph_mdsc_lease_release ceph: don't use ->d_time ...
