[PULL REQUEST] md: various bug fixes
From: Neil Brown
Date: Mon Jun 28 2010 - 00:07:01 EST
Please consider pulling the following changes for 2.6.35.
- fixes for regressions introduced in -rc1 (Restore partition....)
- fixes for enhancements added in -rc1 which were not yet perfect
(mostly relating to 'takeover' of one level by another)
- fixes for bugs of longer standing.
One of these was poor handling of multiple device failure when converting
a RAID5 to a RAID6 with several more devices. This bug exposed
several issues and covers the "md/raid5:*" patches.
The following changes since commit 7e27d6e778cd87b6f2415515d7127eba53fe5d02:
