From 42a73808ed4f30b739eb52bcbb33a02fe62ceef5 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 19 Nov 2007 22:38:33 -0800 Subject: [RAW]: Consolidate proc interface. Both ipv6/raw.c and ipv4/raw.c use the seq files to walk through the raw sockets hash and show them. The "walking" code is rather huge, but is identical in both cases. The difference is the hash table to walk over and the protocol family to check (this was not in the first virsion of the patch, which was noticed by YOSHIFUJI) Make the ->open store the needed hash table and the family on the allocated raw_iter_state and make the start/next/stop callbacks work with it. This removes most of the code. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
