Subject: imsm: FIX: Update function imsm_num_data_members() for Raid1/10
X-Git-Tag: mdadm-3.2.4~29
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=36fd8ccc0e755042e3983a2bd02523461b5f8307;p=thirdparty%2Fmdadm.git

imsm: FIX: Update function imsm_num_data_members() for Raid1/10

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)
