Here we're collecting some funny quotes from the linux kernel code
.owner = THIS_MODULE, /* for consistency 8) */- from linux-2.6.25/net/netlink/af_netlink.c (which is always built-in)
/*
* ...
* Yes, it is a memory overhead, but in 2003 AD, who cares?
*/- from linux-2.6.24/include/linux/netfilter_bridge/ebt_among.h
#define BITS_PER_BYTE 8- from linux-2.6.24/include/linux/bitops.h
/* "NOOP" scheduler: the best scheduler, recommended for all interfaces
under all circumstances. It is difficult to invent anything faster or
cheaper.
*/- from linux-2.6.24/net/sched/sch_generic.c
/*
* Whee.. Weird sysv syscall.
*/- from linux-2.6.24/fs/filesystems.c
static char vlan_copyright[] = "...";
static char vlan_buggyright[] = "...";- from linux-2.6.24-rc5/net/8021q/vlan.c
So... these "amateur" devices are hopeless.
- from linux-2.6.24-rc5/net/ipv4/arp.c:arp_constructor()
/* This code sucks. But you should have seen it before! --RR */- from linux-2.6.23/net/ipv4/route.c
static void dn_long_error_report(struct neighbour *neigh, struct sk_buff *skb)
{
printk(KERN_DEBUG "dn_long_error_report: called\n");
kfree_skb(skb);
}- from linux-2.6.23/net/decnet/dn_neigh.c
/* Unfortunately we don't support this one. Any brave souls? */- from linux-2.6.23/include/linux/skbuff.h:skb_forward_csum()
#define IT_ID_SET 1
#define IT_ID_NOT_SET 0- from linux-2.6.23/kernel/posix-timers.c
* "I ask you, have you ever known what it is to be an orphan?"
*/
static int will_become_orphaned_pgrp(...- from linux-2.6.23/kernel/exit.c
#ifndef I_WISH_WORLD_WERE_PERFECT
/* It is not :-( ...- from linux-2.6.23/net/ipv4/ip_gre.c:ipgre_err()
weird, but documented
- from linux-2.6.23/net/packet/af_packet.c:packet_create()
What the above comment does talk about? --ANK(980817)
- from linux-2.6.23/net/unix/af_unix.c:unix_release_sock()
static inline int sk_hashed(const struct sock *sk)
{
return !sk_unhashed(sk);
}- from linux-2.6.23/include/net/sock.h
Instead of using a dedicated spinlock, we (ab)use inetsw_lock
- from linux-2.6.23/net/ipv4/af_inet.c:build_ehash_secret()
