From 90b7f94812437be10cc3e81bfa10e6c9b6a2e5e2 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Wed, 9 Jan 2019 15:17:09 +0100 Subject: [PATCH] libceph: fix CEPH_FEATURE_CEPHX_V2 check in calc_signature() 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.
