Will there be pagemap support tools and libraries available in future versions of Red Hat Enteprise Linux?

Issue

• Customers require a set of userspace libraries and / or tools that will allow them to leverage the pagemap interface in the RedHat Enterprise Linux 6 kernel.
• Information about pagemap in the kernel docs: http://www.mjmwired.net/kernel/Documentation/vm/pagemap.txt
• Example utilities: http://selenic.com/repo/pagemap/
• A couple of use cases:
  • http://www.eqware.net/Articles/CapturingProcessMemoryUsageUnderLinux/index.html
  • http://olivergerlich.wordpress.com/2009/01/09/2-gigs-of-memory-pixelized/
• Customer is seeking a better delineation of how much memory processes are actually using.
• pagemap bits appear to be in the kernel, but there are no supporting tools or libraries that help take advantage of it.
