Subject: [PATCH 2/2] Bugfix: xt_hashlimit does a wrong SEQ_SKIP.

From: Jesper Dangaard Brouer <[email-masked]>
Date: Tue, 26 May 2009 15:18:57 +0200

(Inside net/netfilter/xt_hashlimit.c)
The function dl_seq_show() returns 1 (equal to SEQ_SKIP) in case
a seq_printf() call return -1.  It should return -1.

This SEQ_SKIP behavior brakes processing the proc file e.g. via a
pipe or just through less.
