Virtualization - Nov 2010 - Announce: Auto/Lazy-migration Patches RFC on linux-numa list

At last weeks' LPC, there was some interest in my patches for Auto/Lazy
Migration to improve locality and possibly performance of unpinned guest
VMs on a NUMA platform.  As a result of these conversations I have reposted
the patches [4 series, ~40 patches] as RFCs to the linux-numa list.  Links
to threads given below.

I have rebased the patches atop 3Nov10 mmotm series [2.6.36 + 3nov mmotm].
The patched kernel builds, boots and survives some fairly heavy testing on
an 8 node istanbul x86_64.  Under heavy load, I do encounter a race in the
somewhat optional migration cache.  Currently this generates a warning and
carries on, but the one migration cache entry and related page is then
wedged.  This would need to be resolved.
