From 92850bbd71228730c80efd491e7427650188d359 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 21 Oct 2008 13:25:32 +1100 Subject: [PATCH] md: allow extended partitions on md devices. The new extended partition support provides a much nicer was to have partitions on md devices that the 'mdp' alternate major. We cannot really get rid of 'mdp' at this time, but we can enable extended partitions as that will probably make life easier for sysadmins.
