cem f219735807 vm_fault_hold: handle vm_page_rename failure ... On vm_page_rename failure, fix a missing object unlock and a double free of a page. First remove the old page, then rename into other page into first_object, then free the old page. This avoids the problem on rename failure. This is a little ugly but seems to be the most straightforward solution.
