New week, new status update...
The details are at http://www.kernelnewbies.org/status/
With the code freeze date approaching soon, it is obvious that many of these projects will not get merged in the next 3 months. What would you rather me do? Keep them in here just for reference, mark them as post-code freeze or just delete them?
Let me know what you think,

I think that you have more than 3 months to continue updating this. :)

It would actually be useful to have some more people propose input on Guillaume's list at some point, or even to suggest removal of items unlikely to happen.

There's also a lot of cross-over with this item and the x86 subarch support which James Bottomley has been working on. I've been kicking that patch around a little the last few days, and I'll be merging it soon, so we can get a taste for how arch/i386/ *could* look.

That is correct. And, for a feature, we only need a header file to be in, right? ;)

Please don't. While it would be nice if x86 init were a bit nicer, and things like CPUs were added in a 'hotpluggable' manner, I won't be dedicating time to this. At least not in near future...

Hmmmmmm 8-)
wrt to post-halloween features, things like new drivers that require no core changes aren't an issue, but things like ripping out the VM and replacing with a new one should probably wait until 2.6.10 or so.[*]

Rusty seems to have a good handle on the hotplug bits, whether bringing them up in a hotplug manner is his intention I'm not sure, but it does seem to be going in that direction afaics.

[*] j/k of course. (at least, I hope so).

Please keep them as post-code freeze. They might not go into 2.5 and early 2.6, but that doesn't mean we should throw away our TODO list ;)

Indeed. It may even be an idea to take what I started doing at
http://www.codemonkey.org.uk/Linux-2.5.html, merging the two and Guillaume running with this if you have time, because these days, between hacking and merging patches, I'm kept pretty busy, so updates to that file are getting less frequent.

I would like to be able to do more to help the community, and in particular you Dave as feature freeze for 2.6 approaches and it becomes critical to track things down, but unless a Linux company out there can sponsor me, I just won't be able to dedicate more time than I am already dedicating to this.
Doing a good job at tracking a gazillion items and bugging people about patches and status is just incredibly time consuming.
