    [INET]: Collect frag queues management objects together · 7eb95156
    Pavel Emelyanov authored
    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.
