Subject: [PATCH 0/3] make mapped executable pages the first class citizen (with test cases)
Date: Mon, 08 Jun 2009 17:10:44 +0800	[thread overview]
Message-ID: <20090608091044.880249722@intel.com> (raw)

Andrew,

I managed to back this patchset with two test cases :)

They demonstrated that
- X desktop responsiveness can be *doubled* under high memory/swap pressure
- it can almost stop major faults when the active file list is slowly scanned
  because of undergoing partially cache hot streaming IO

The details are included in the changelog.

Thanks,
Fengguang
