From 7eb95156d9dce2f59794264db336ce007d71638b Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 15 Oct 2007 02:31:52 -0700 Subject: [INET]: Collect frag queues management objects together There are some objects that are common in all the places which are used to keep track of frag queues, they are: * hash table * LRU list * rw lock * rnd number for hash function * the number of queues * the amount of memory occupied by queues * secret timer Move all this stuff into one structure (struct inet_frags) to make it possible use them uniformly in the future. Like with the previous patch this mostly consists of hunks like - write_lock(&ipfrag_lock); + write_lock(&ip4_frags.lock); To address the issue with exporting the number of queues and the amount of memory occupied by queues outside the .c file they are declared in, I introduce a couple of helpers.
