  23  * This tests priv_gettext(). The priv_gettext() function always falls back to
  24  * the C locale if it can't find anything. To deal with that, we've defined a
  25  * dummy translation for the zz_AA.UTF-8 locale which has a translation for the
  26  * 'dtrace_kernel' privilege.
  27  *
  28  * Normally 'dtrace_kernel' has the following description:
  29  *
  30  *   Allows DTrace kernel-level tracing.
  31  *
  32  * In the zz_AA.UTF-8 locale it has the following description:
  33  *
  34  *   Ah Elbereth Gilthoniel
  35  *
  36  * We explicitly verify that things respect the global locale and per-thread
  37  * locale.
