Konstantin Belousov c62637d679 Correct vm_fault_copy_entry() handling of backing file truncation ... after the file mapping was wired. if a wired map entry is backed by vnode and the file is truncated, corresponding pages are invalidated. vm_fault_copy_entry() should be aware of it and allow for invalid pages past end of file. Also, such pages should be not mapped into userspace. If userspace accesses the truncated part of the mapping later, it gets a signal, there is no way kernel can prevent the page fault.
