And for reference, here's my current list (not yet collated with yours).  In 
theory, both of these will feed into Guillaume's current list.  What's going 
to feed into Linus's current list is anybody's guess...

Jeff Garzik tells me zerocopy NFS is merged already.

Linus returns from the Linux Lunacy Cruise after Sunday, October 27th.
(By the time you read this, he should be in Cozumel, Mexico.  En route
to Grand Cayman, Jamaica, the Bahamas, and Ft Lauderdale.  See
http://www.geekcruises.com/itinerary/ll2_itinerary.html )

The following features aim to be ready for submission to Linus by Monday,
October 28th, to be considered for inclusion (in 2.5.45) before the feature
freeze on Thursday, October 31 (halloween).

Note: if you want to submit a new entry to this list, PLEASE provide a URL
to where the patch can be found, and any descriptive announcement you think
useful (user space tools, etc).  This doesn't have to be a web page devoted
to the patch, if the patch has been posted to linux-kernel a URL to the post
on any linux-kernel archive site is fine.

If you don't know of one, a good site for looking at the threaded archive is:
http://lists.insecure.org/lists/linux-kernel/
and a more searchable archive is available at:
http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&group=mlist.linux.kernel

This list is just pending features trying to get in before feature freeze.
If you want to know what's already gone in, or what's being worked on for
the next development cycle, check out "http://kernelnewbies.org/status".

You can get Andrew Morton's MM tree here:

And Alan Cox's -ac tree here:

======================== Unresolved issues: =========================

1) Kernel Probes  (Vamsi Krishna S)

Is this the same as dynamic probes?

2) Unified boot/parameter support (Rusty Russell)
3) Hotplug CPU removal (Rusty Russell)

Patches are available under:

http://www.kernel.org/pub/linux/kernel/people/rusty/patches

But there are a lot of them, and it's not quite clear what to
apply in what order.  (I know Linus likes 'em broken up, but
an description and a pointer to a roll-up patch would be nice
for civilian testers.  I moved the in-kernel module loader to
the main list because I found an announcement posting for it.)

4) hyperthread-aware scheduler
5) connection tracking optimizations.

No URLs to patch.  Anybody want to come out in favor of these
with an announcement and pointer to a version being suggested
for inclusion?

6) IPSEC (David Miller, Alexy)
7) New CryptoAPI (James Morris)

David S. Miller said:

> No URLs, being coded as I type this :-)

> Some of the ipv4 infrastructure is in 2.5.44

Note, this may conflict with Yoshifuji Hideyaki's ipv6 ipsec stuff.  If not,
I'd like to collate or clarify the entries.)  USAGI ipv6 is in the first
section and this isn't because I have a URL to an existing patch to
USAGI, and don't for this.  I have no idea how much overlap there is
between these projects, and whether they're considered parts of the
same project or submitted individually...

8) ReiserFS 4

Hans Reiser said:

See also http://www.namesys.com/v4/fast_reiser4.html

Hans and Jens Axboe are arguing about whether or not Reiser4 is a
potential post-freeze addition.  That thread starts here:

http://lists.insecure.org/lists/linux-kernel/2002/Oct/7140.html

9) 32bit dev_t

Alan Cox said:

> The big one missing is 32bit dev_t. Thats the killer item we have left.

But did not provide a URL to a patch. :)

He also mentioned:

> Oh other one I missed - DVB layer - digital tv etc. Pretty much
> essential now for europe, but again its basically all driver layer

But it's not clear this is an item that must go in before feature freeze
or not at all.

10) initramfs

It may be on its way in already.  See:
http://lists.insecure.org/lists/linux-kernel/2002/Oct/1110.html
