Subject: Create:  Don't optimise resync as recovery when creating raid5 in a container.
X-Git-Tag: mdadm-3.0-devel2~15
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=87b47257eb5605b4f96772405368ea3db3fcf9c3;p=thirdparty%2Fmdadm.git

Create:  Don't optimise resync as recovery when creating raid5 in a container.

As spares are treated quite differently in containers, we cannot
fake-up a spare to optimise initialisation for a raid5 in a container,
so disable that code for ->external arrays.
