Subject: [PATCH 0/2] numa/core updates
Date: Sun,  2 Dec 2012 17:13:14 +0100	[thread overview]
Message-ID: <1354464796-14343-1-git-send-email-mingo@kernel.org> (raw)

I've been testing wider workloads and here's two more small and
obvious patches rounding up numa/core behavior around the edges.

The NUMA code should now be pretty unintrusive to all but the
long-running, memory-intense workloads where it's expected to
make a (positive) difference.

Short-run workloads like kbuild or hackbench don't trigger the
NUMA code now. The limits can be reconsidered later on,
iteratively - the goal now is to not regress.

Thanks,

	Ingo
