From e919fb0af245512b02200b8e78c8bbbc0f966f9c Mon Sep 17 00:00:00 2001 From: Adam Kwolek Date: Wed, 8 Jun 2011 17:13:26 +1000 Subject: [PATCH] FIX: Enable metadata updates for raid0 When raid0 is takeovered to degraded raid4, metadata updates has to be applied via mdmon (raid4 has to be monitored). It is not possible due to no update_tail pointer initialization in supertype structure.
