Subject: [NETFILTER 34/38]: nf_conntrack_sctp: remove timeout indirection
Date: Tue, 15 Jan 2008 07:19:58 +0100 (MET)	[thread overview]
Message-ID: <20080115061953.3184.11875.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20080115061907.3184.39432.sendpatchset@localhost.localdomain>

[NETFILTER]: nf_conntrack_sctp: remove timeout indirection

Instead of keeping pointers to the timeout values in a table, simply
put the timeout values in the table directly.
