- A relatively small number of changes, although we're up to 9MB of diff
  in the various git trees.



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@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.

These are wrong.  The hardware is not available so -ENODEV is the right
return value.  Especially in the mmtimer case this is a real bug because
the module would stay loaded despite not beeing initialized and uneeded,
in the others it's just cosmetical but still wrong.

OK, thanks, gone.

I changed that initcall warning so it doesn't warn about -ENODEV unless you
specified initcall_debug.

Oh, BTW ... I see that's also broken in -git9, but not -git8.

Presumably something didn't go via -mm for testing?

No, it's just that we suck.  The numa-maps update got squeezed in at the
last minute.

I guess we do it this way - there's still code in there which will call
check_huge_range(), but it's inside if (0) {}.

Yeah, that won't be needed for a link, but it's needed to avoid a compile
warning.

Just for the record; the slab corruption I was seeing with
2.6.16-rc5-mm2 does not occour with this kernel.
After a lot of rebuilds and very good bug hunting by various people we
found the offensive patch and it seems you removed it from -mm -
thanks.

Seen during early boot from the initrd, while the initrd was firing up a
'lvm vgscan' to get the root filesystem accessible.. 2.6.15-rc5-mm2 didn't do this.

Thanks.  Those patches are being redone.

Jun'ishi-san, please ensure that they're tested with CONFIG_PREEMPT and all
debug options turned on.

Oops, thank you for testing and reporting.
I'll make sure to test with CONFIG_PREEMPT.

Hi there,

-mm3 failed to boot on sempro box[1], after lilo, screen went blank, 
no response... hit reset to reboot...  Same config as -mm2 which did 
boot okay.

Applying "revert-x86_64-mm-i386-early-alignment.patch" fixed it here too.
(CPU is Sempron SktA 32-bit)

[1] http://bugsplatter.mine.nu/test/linux-2.6/sempro/ for dmesg & config
from -mm2

If you create a function in one file and call them from another file you 
need a prototype in a header file or bad runtime errors can occur in 
some cases.

You mustn't ignore warnings about implicitely defined functions.
This bug was found by the gcc -Werror-implicit-function-declaration flag 
that turns such warnings into errors.

Why did dlm_lockres_master_requery() become global?

It is neither used in another file nor does any of the changeset 
descriptions escribe it.

The importer hit a snag and didn't get the last three -mm kernels or so.
Should fix itself during the next few hours.

Please tell me directly if there's a problem; usually, new -mm releases
should be available as git trees 2h after an announcement.

I just encountered a memleak, this is a laptop and i use swsusp (I am not
sure if it is related but since the memleak involves task_struct).

Let me know if you need any other informations, i'll see if it is
reproducable in the next days.

regards.

[PATCH] libata: fix missing classes[] initialization in ata_bus_probe()

[Tejun Heo]

ata_bus_probe() didn't initialize classes[] properly with
ATA_DEV_UNKNOWN.  As ->probe_reset() is allowed to leave @classes
alone when no device is present, this results in garbage class values.
ATM, the only affected driver is ata_piix.

Cc: Jiri Slaby <jirislaby@gmail.com>

Jiri, thanks for reporting this.  The offending change has been there
for some time but it's the first time I see it.  Probably because my
garbage was never ATA_DEV_ATA or ATA_DEV_ATAPI.
