Merge tag 'ceph-for-4.9-rc5' of git://github.com/ceph/ceph-client 

Pull Ceph fixes from Ilya Dryomov:
 "Ceph's ->read_iter() implementation is incompatible with the new
  generic_file_splice_read() code that went into -rc1.  Switch to the
  less efficient default_file_splice_read() for now; the proper fix is
  being held for 4.10.

  We also have a fix for a 4.8 regression and a trival libceph fixup"

* tag 'ceph-for-4.9-rc5' of git://github.com/ceph/ceph-client:
  libceph: initialize last_linger_id with a large integer
  libceph: fix legacy layout decode with pool 0
  ceph: use default file splice read callback
