The latest 2.5 status update is available at

Only 3 weeks left till Halloween, and still way to many
items left on the list to be merged in that timeframe.
Come on, be real and tell me what to remove! :-)

I think these ones are in -mm already.

This one seems nearly ready.

Reclassify as beta ?

There is some code around, but there are a ton of other
things asking for attention at the moment ;(

I'd say this is "ready" state now.

Beta.

Drop this, I don't think it'll make it in time. I ended up spreading
the mem-map array across nodes by hand for 32 bit machines.

Alpha, and it's Manfred Spraul doing most of the real work on
this now ;-)

Beta.

There's been a lot of discontigmem cleanup over the 2.5.3x timeframe
by both myself and Christoph.

Um, you removed two items I reported as done and merged since the last
time you posted one of these.
Bill
Did I??? Ooops... not intended, sorry about that.
I had put them on hold to find out from you which
version they had been merged at (couldn't find it in the
log) and then forgot about it.
If you can give me the info, I'll put them back.
Thanks,

Remove (iteration over) global tasklist (Ingo, me):
merged 2.5.37
Parallelizing page replacement (velco, akpm, dhansen, me):
last steps of the per-zone LRU lists, locks, and per-node
kswapd's merged as of 2.5.40, per-inode pagecache locking
merged centuries ago (with the ratcache).

This should be moved to Ready. We've posted 2.5.40 patches,
and the 2.5.41 patches are available at:
http://lkcd.sourceforge.net/download/4.2pre/kernel
These have been tested by teams in India and the U.S. on lots
of different systems.
We'll keep patching them forward until they're incorporated. We
have fixed Andi Kleen and Randy Dunlap's issues with the 2.5.40
drivers for 2.5.41. I've also sent a request to Linus to have
them incorporated. Copying him again.
We're ready to go.
