  Log:
  SVN rev 192144 on 2009-05-15 14:41:44Z by kib
  
  Revert r192094. The revision caused problems for sysctl(3) consumers
  that expect that oldlen is filled with required buffer length even when
  supplied buffer is too short and returned error is ENOMEM.
  
  Redo the fix for kern.proc.filedesc, by reverting the req->oldidx when
  remaining buffer space is too short for the current kinfo_file structure.
  Also, only ignore ENOMEM. We have to convert ENOMEM to no error condition
  to keep existing interface for the sysctl, though.
