Subject: Set reshape.after.data_disks for raid0<->raid10 takeover
X-Git-Tag: mdadm-3.2~70
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=031d445c18a91eb140ce87cd05b0d3fec1f1b215;p=thirdparty%2Fmdadm.git

Set reshape.after.data_disks for raid0<->raid10 takeover

reshape.after.data_disks field must be initiated
for raid0<->raid10 transition.
Instead calculated spares_needed variable in reshape_array
function has random value.
