Subject: [PATCH] md: do not count journal as spare in GET_ARRAY_INFO
Date: Thu, 11 Aug 2016 17:14:45 -0700	[thread overview]
Message-ID: <1470960885-2860586-1-git-send-email-songliubraving@fb.com> (raw)

GET_ARRAY_INFO counts journal as spare (spare_disks), which is not
accurate. This patch fixes this.
