Hi Christoph, Thanks for the pointers, but as you've been debating for 18 months now, no patches are in the -mm tree or obviously about to go in, and this new helper function is orthogonal to your work, I don't think it's reasonable to delay this patch. All we can reasonably do is push this function back into the xen part of the kernel tree for now. Rusty. -- Help!
