While it's great that you tell the stable people about this, but is it realistic? Is anyone using Xen as contained in the mainline kernel these days?
If a distro were to be based on 2.6.25 and we take this patch, they will just revert it back out due to their very large Xen patchset they apply on top to get a "working" Xen version, right?
