Subject: [PATCH 04/12] libxtables: avoid running into .also checks when option not used
Date: Fri, 13 May 2011 02:47:28 +0200	[thread overview]
Message-ID: <1305247657-29158-5-git-send-email-jengelh@medozas.de> (raw)
In-Reply-To: <1305247657-29158-1-git-send-email-jengelh@medozas.de>

If a particular option was not specified, it should not be subject to
.also checks in xtables_option_fcheck2 either.
