    Merge tag 'ceph-for-4.8-rc1' of git://github.com/ceph/ceph-client · 72b5ac54
    Linus Torvalds authored
    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"
