    sys/vm               device_pager.c 
  Log:
  The addition of a locking assertion to vm_page_zero_invalid() has revealed
  a long-time bug: vm_pager_get_pages() assumes that m[reqpage] contains a
  valid page upon return from pgo_getpages().  In the case of the device
  pager this page has been freed and replaced by a fake page.  The fake page
  is properly inserted into the vm object but m[reqpage] is left pointing
  to a freed page.  For now, update m[reqpage] to point to the fake page.
