Subject: [PATCH 0/5] Memory policy corruption fixes -stable
Date: Tue, 9 Oct 2012 17:58:36 +0100 [thread overview]
Message-ID: <1349801921-16598-1-git-send-email-mgorman@suse.de> (raw)
This is a backport of the series "Memory policy corruption fixes V2". This
should apply to 3.6-stable, 3.5-stable, 3.4-stable and 3.0-stable without
any difficulty. It will not apply cleanly to 3.2 but just drop the "revert"
patch and the rest of the series should apply.
I tested 3.6-stable and 3.0-stable with just the revert and trinity breaks
as expected for the mempolicy tests. Applying the full series in both case
allowed trinity to complete successfully. Andi Kleen reported previously
that the series fixed a database performance regression[1].
