Subject: md: do not count journal as spare in GET_ARRAY_INFO
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b347af816ad2086c1dacf9f74973b82f83e877be;p=deliverable%2Flinux.git

md: do not count journal as spare in GET_ARRAY_INFO

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