Subject: imsm: allow to specify second volume size
X-Git-Tag: mdadm-4.2-rc1~90
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1a1ced1e2e64a6b4b349a3fb559f6b39e4cf7103;p=thirdparty%2Fmdadm.git

imsm: allow to specify second volume size

Removed checks which limited second volume size only to max value (the
largest size that fits on all current drives). It is now permitted
to create second volume with size lower then maximum possible.
