- this has everything which is in 2.6.21. Plus more!

- a number of nasty bugs were fixed. This should be (a lot) more stable
than 2.6.21-rc7-mm1.

Some sysfs-related problems are still expected. Fiddling with the
setting of CONFIG_SYSFS_DEPRECATED might help avoid them.

- the 64-bit futex patches and (consequently) the private-futex patches were
dropped. Because the 64-bit futex patches need to be reconstituted.

- the unprivileged mounts code was dropped, pending an updated patch series

- lots of minor fbdev bugs were fixed


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@xxxxxxxxxxxxxxx

- 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.
