Subject: [PATCH] md-cluster: correct the num for comparison
Date: Fri, 10 Apr 2015 16:06:12 +0800 [thread overview]
Message-ID: <1428653172-12678-1-git-send-email-gqjiang@suse.com> (raw)
From: Guoqing Jiang <gqjiang@suse.com>
Since the node num of md-cluster is from zero, and
cinfo->slot_number represents the slot num of dlm,
here also need to deduct one to keep consistency
with other codes.
