Unrelated report, dtrace complains about this probe on my stable/13 system:
     failed to resolve translated type for args[0]

And I do not have any idea why...

 From ctfdump:
   [27290] FUNC (vm_page_unwire) returns: 38 args: (1463, 3)

   <1463> TYPEDEF vm_page_t refers to 778
   <778> POINTER (anon) refers to 3575
   <3575> STRUCT vm_page (104 bytes)
