  crush: remove redundant local variable (2016-10-05 23:02:10 +0200)

----------------------------------------------------------------
The big ticket item here is support for rbd exclusive-lock feature,
with maintenance operations offloaded to userspace (Douglas Fuller,
Mike Christie and myself).  Another block device bullet is a series
fixing up layering error paths (myself).

On the filesystem side, we've got patches that improve our handling of
buffered vs dio write races (Neil Brown) and a few assorted fixes from
Zheng.  Also included a couple of random cleanups and a minor CRUSH
update.

      rbd: add rbd_obj_request_error() helper
      libceph: use CEPH_AUTH_UNKNOWN in ceph_auth_build_hello()
      libceph: ceph_build_auth() doesn't need ceph_auth_build_hello()
      crush: don't normalize input of crush_ln iteratively
      crush: remove redundant local variable
