Subject: [PATCH 01/14] imsm: FIX: Update function imsm_num_data_members() for Raid1/10
Date: Fri, 13 Apr 2012 16:51:55 +0200	[thread overview]
Message-ID: <1334328728-12544-2-git-send-email-adam.kwolek@intel.com> (raw)
In-Reply-To: <1334328728-12544-1-git-send-email-adam.kwolek@intel.com>

Function imsm_num_data_members() returns wrong value for raid 1 and 10.
It returns all data member but it should return number of unique data
members (excluding mirror devices)
