Actually, the version of change_hatv patch I committed included the
suggestion from you, John, to make both the entry and exit calls
be change_hatv(), so no, even if you include trunk rev 2337 (the
change_hatv patch), mod_apparmor should still work with a libapparmor
without the format string fix incorporated.
