Subject: [PATCH 46/63] mm: numa: Do not group on RO pages
Date: Mon,  7 Oct 2013 11:29:24 +0100	[thread overview]
Message-ID: <1381141781-10992-47-git-send-email-mgorman@suse.de> (raw)
In-Reply-To: <1381141781-10992-1-git-send-email-mgorman@suse.de>

From: Peter Zijlstra <peterz@infradead.org>

And here's a little something to make sure not the whole world ends up
in a single group.

As while we don't migrate shared executable pages, we do scan/fault on
them. And since everybody links to libc, everybody ends up in the same
group.
