I realise 3 weeks is only just up but I'm wondering if you intend to MFC this (and hopefully r238456) soon. I've had a quick try at merging this back to 8.x but it relies on vm_pageout_page_lock() and vm_page_unlock() which were added in r207694 and I'm not sure about the impact of merging that. -- Peter Jeremy
