Subject: DDF: use array_size from metadata.
X-Git-Tag: mdadm-3.3.1~33
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=55e0007423ef93c331844a7b64dec326dc692e95;p=thirdparty%2Fmdadm.git

DDF: use array_size from metadata.

If some other controller sets a number smaller than a calculation
would give us, we really should honour it.
