Message-ID: <20110520161448.375eb634@endymion.delvare> Date: Fri, 20 May 2011 16:14:48 +0200 From: Jean Delvare <khali@...ux-fr.org> To: LKML <linux-kernel@...r.kernel.org> Cc: Andrew Morton <akpm@...ux-foundation.org> Subject: [PATCH] check_signature depends on CONFIG_CHECK_SIGNATURE check_signature() is only available if CONFIG_CHECK_SIGNATURE has been selected. Don't declare the function if it won't be available at link time. That way, any failure to select CONFIG_CHECK_SIGNATURE as needed will show up immediately at build time.
