[Andrew just released another -mm while I was typing this one up]

I've been hunting down some hard-to-catch reboots in the last two -mm releases 
that leave no traces in the log other than an abrupt halt of all logging, at 
first I thought I was chasing a Netfilter problem but after a few days of full 
Netfilter debugging on, I came to the conclusion that the problem wasn't 
necessarily Netfilter specific as I was still seeing reboots with no Netfilter 
errors logged immediately before the crash.  With most of the debugging options 
turned on in "Kernel Hacking" and the machine running like a dog for a few days, 
it seemed stable (unfortunately).

Anyway, I might have finally hit the jackpot this time, as it only ever seemed 
to crash when I was at work.  But I'm here, and it just did it...

I'll build an rc2-mm1 now and see how we go, but I guess it'd still be good to 
know if this one was ever fixed or not.

2.6.16-rc1-mm5

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16-rc1/2.6.16-rc1-mm5/


- The ntp/time rework patches from John Stultz have been resurrected and fixed.

- There's now a `hot-fixes' directory at the above URL.  Please look in
  there for any updates which should be applied.


Known problems:

- Sam has added a new check in the kbuild tree.  It detects multiple
  instances of EXPORT_SYMBOL(foo) across separate .o files.

  It catches a _lot_ of problems.   You'll see something like this:

WARNING: vmlinux: duplicate symbol '__down_interruptible' previous definition was in vmlinux
WARNING: vmlinux: duplicate symbol '__down' previous definition was in vmlinux
WARNING: vmlinux: duplicate symbol '__up' previous definition was in vmlinux
WARNING: vmlinux: duplicate symbol 'smp_call_function' previous definition was in vmlinux
WARNING: vmlinux: duplicate symbol 'iounmap' previous definition was in vmlinux
WARNING: vmlinux: duplicate symbol '__ioremap' previous definition was in vmlinux
WARNING: vmlinux: duplicate symbol 'ioremap' previous definition was in vmlinux
WARNING: vmlinux: duplicate symbol 'sys_ctrler' previous definition was in vmlinux

  There's probably not a lot of point in reporting this if you see it.

  Patches would be nice, but be warned that fixing these is not as trivial
  as one might think:

  - If one export is in generic code and the other is in arch code then

    - If you remove the export in generic code, you need to check all
      architectures for breakage.

    - If you remove the export in arch code then you need to be sure
      that the generic .o file a) always compiles in the offending function
      and b) is always linked into vmlinux.

  - If both exports are in arch code then you need to ensure that
    the export which isn't deleted is always included in vmlinux when
    the symbol which it exports is included in vmlinux.

  If possible, the best approach is to put the EXPORT_SYMBOL
  immediately after the symbol which is being exported.  And if it's
  a function, pleeeze don't put a blank line between the end of the
  function and the export - I've no idea why people do that...


Boilerplate:

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

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

- If you hit a bug in -mm and it's 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.

It runs fine here, no problems. Even iptables works this time.

Actually it spoke too fast, I have the following oops with
CONFIG_DEBUG_INITDATA=y (it does not oops without this config
option).

I can send full dmesg and .config if needed (the bug is reproducable).

with gcc4.1 (I supposed buffered_rmqueue is inlined):

Ahem, I don't think I actually tested that.

This would seem to be needed, but I don't think it'll fix that one.

Don't touch page_state[not-possible-CPU].

You can also use the mm->git tree (at .../linux/kernel/git/smurf/
/linux-trees.git) and use "git bisect".

It'll be a bit slower, but the upside is that it's able to descend into
the git trees which Andrew has imported into mm as monolithic patches.

Sigh. I did a 'make allmodconfig' on x86_64 and found to my suprise only
a sinlge symbol being exported more than one time.

This is purely a consistency check introduced by commit:

I can rip it out again if the noise/value ratio is too high.

We should IMO try to keep the exports in generic code.
The exports should go with the function definition - right after closing
'{'.
All other ways of exporting function is a call for inconsistency.
A gret deal of effort has been put into getting rid of ksym files
- good. But exports should not be scattered far away form the function
definition.

Placing the export just below the function definition should cover this
in 90% of the cases. The rest is macros..

Agreed.

No, let's keep it.  We're wasting memory on this stuff.

> We should IMO try to keep the exports in generic code.

Yes, I guess so.  It gets tricky when you get onto things like the string
functions, most of which may be impemented in generic code or may be in
arch code, depending on __ARCH_HAVE_stuff.
