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.
