  Modified files:
    sys/kern             kern_descrip.c 
  Log:
  Fix fdcheckstd to pass the file descriptor along through vn_open. When
  opening a device, devfs_open needs the file descriptor to install its
  own fileops. Failing to pass the file descriptor causes the vnode to
  be returned with the regular vnops, which will cause a panic on the
  first read or write because devfs_specops is not meant to support
  those operations.
  
  This bug caused a panic after exec'ing any set[ug]id program with
  fds 0..2 closed (i.e., if any action had to be taken by fdcheckstd, we
  would panic if the exec'd program ever tried to use any of those
  descriptors).
