Subject: md: Fix regression with raid1 arrays without persistent metadata.
X-Git-Tag: v2.6.37-rc1~43^2~12
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d97a41dc9c44f5829b7af7aa69fda10fd82b6b4e;p=pandora-kernel.git

md: Fix regression with raid1 arrays without persistent metadata.

A RAID1 which has no persistent metadata, whether internal or
external, will hang on the first write.
This is caused by commit  070dc6dd7103b6b3f7e4d46e754354a5c15f366e
In that case, MD_CHANGE_PENDING never gets cleared.

So during md_update_sb, is neither persistent or external,
clear MD_CHANGE_PENDING.

This is suitable for 2.6.36-stable.
