  r315595:
  
  Remove a commented out line before kvm_getprocs(3)
  
  The commented out return value for kvm_getprocs(3) was misleading -- the
  uncommented line is correct.
  
  No content change
  
  r315603:
  
  kvm_close(3): return `error` instead of blindly returning `0`
  
  `error` is the accumulated error from previous close(2) calls.
  
  This bug has been present since the libcall's import from 4.4BSD
  Lite (r1573).
