To:	linux-kernel@...r.kernel.org
Subject: 2.6.21-rc3-mm1


Temporarily at

  http://userweb.kernel.org/~akpm/2.6.21-rc3-mm1/

Will appear later at

  ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.21-rc3/2.6.21-rc3-mm1/



- The wireless changes in here need a lot of testers, please.  It is major
  rework.

  Of course the config files got all changed around so `make oldconfig'
  breaks everything.  I was able to get ipw2200 working after some fumbling,
  but perhaps John can tell people what has been changed in there?  What has
  happened, from a big picture perspective?

- This patchset contains Con's rip-up-and-rewrite of the CPU scheduling
  algorithm.  It oopsed for me on one machine so I'll do an rc3-mm2 without
  those changes shortly.  If 2.6.21-rc3-mm1 crashes and 2.6.rc3-mm2 does not,
  don't forget to Cc: Con Kolivas <kernel@...ivas.org> on the report ;)

  Feedback on this change is sought.  Especially from the
  enterprise-database and volanomark loonies: this stuff might be headed your
  way so don't tell us afterwards that it hurt.

- Added Nick's lock-the-page-in-the-pagefault-handler patches.  These reduce
  the incidence of one bug and increase the incidence of another.  VM is fun. 

- Re-added the ext4 development tree to the -mm lineup.  It has stuff in
  it.  



Boilerplate:

- See the `hot-fixes' directory for any important updates to this patchset.

- To fetch an -mm tree using git, use (for example)

  git-fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git tag v2.6.16-rc2-mm1
  git-checkout -b local-v2.6.16-rc2-mm1 v2.6.16-rc2-mm1

- -mm kernel commit activity can be reviewed by subscribing to the
  mm-commits mailing list.

        echo "subscribe mm-commits" | mail majordomo@...r.kernel.org

- If you hit a bug in -mm and it is not obvious which patch caused it, it is
  most valuable if you can perform a bisection search to identify which patch
  introduced the bug.  Instructions for this process are at

        http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt

  But beware that this process takes some time (around ten rebuilds and
  reboots), so consider reporting the bug first and if we cannot immediately
  identify the faulty patch, then perform the bisection search.

- When reporting bugs, please try to Cc: the relevant maintainer and mailing
  list on any email.

- When reporting bugs in this kernel via email, please also rewrite the
  email Subject: in some manner to reflect the nature of the bug.  Some
  developers filter by Subject: when looking for messages to read.

- Occasional snapshots of the -mm lineup are uploaded to
  ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/mm/ and are announced on
  the mm-commits list.
