From f0ca340cd20b350eab8288974e9a6077900846e8 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 2 Feb 2006 14:28:04 -0800 Subject: [PATCH] [PATCH] md: Make sure array geometry changes persist with version-1 superblocks super_1_sync only updates fields in the superblock that might have changed. 'raid_disks' and 'size' could have changed, but this information doesn't get updated.... until this patch.
