- We're getting a relatively large number of crash reports coming out of the
core sysfs/kobject/driver/bus code, and they're all really hard to diagnose.

I am suspecting that what's happening is that some registration functions
are failing and the caller is ignoring that failure. The code proceeds and
crashes much later, in obscure ways.

All these functions return error codes, and we're not checking them. We
should. So there's a patch which marks all these things as __must_check,
which causes around 1,500 new warnings.

These are all bugs and they all need to be fixed.

In some cases (eg, sysfs file removal) there's not a lot the caller can do
apart from warn, so we should probably change those things to return void
and put a diagnostic message into the callee itself.

These new warnings can be turned off with CONFIG_ENABLE_MUST_CHECK=n, but
I'll probably drop that patch. There's just no excuse for ignoring error
codes and then blundering on to crash.

- There are some improvements to the swsusp disk IO handling. You should
find that the suspend-time writeout and resume-time readin speeds are
approximately doubled.

- reiser4 doesn't build, due to changes in

vectorize-aio_read-aio_write-fileop-methods.patch
remove-readv-writev-methods-and-use-aio_read-aio_write.patch
streamline-generic_file_-interfaces-and-filemap.patch

- You'll probably see these:

WARNING: drivers/net/3c59x ids 36 bad size (each on 16)
WARNING: drivers/net/depca ids 24 bad size (each on 16)
WARNING: drivers/net/dgrs ids 24 bad size (each on 16)

They're triggered by eisa-bus-modalias-attributes-support-1.patch but I
don't know where the error lies. But I love the error message! Would be
good to see on a tee shirt.

- powerpc (on Mac G5's at least) appears to be dead, probably due to the
interrupt management changes in 2.6.18-rc1.

- please read the "Boilerplate", below. Especially the last point.



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 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.
