4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ilya Dryomov <idryomov@xxxxxxxxx>
Upstream commit cc255c76c70f ("libceph: implement CEPHX_V2 calculation
mode") was adjusted incorrectly: CEPH_FEATURE_CEPHX_V2 if condition got
inverted, thus breaking 4.9.144 and later kernels for all setups that
use cephx.
