Temporarily at

  http://userweb.kernel.org/~akpm/2.6.20-mm2/

Will appear later at

 ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.20/2.6.20-mm2/


- There are IDE- and Xen-related module linkage errors during allmodconfig
  builds.  These have been reported.

- Quite a lot of less-popular architectures are broken by the utrace merge. 
  They will stay that way while the maintainers ponder
  http://people.redhat.com/roland/utrace/utrace-arch-porting-howto.txt

- Added the LED development tree to the -mm lineup as git-leds.patch
  (Richard Purdie <rpurdie@rpsys.net>)

- git-parisc.patch is back for a while

- git-audit.patch is back for a while

- git-drm.patch is still in disgrace

- Added Xen domain-U support

- Judging by the number of times I get asked "is there a git tree for -mm",
  nobody is reading the boilerplate.  Here it is again:



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@vger.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.

Okay I think I've fixed it up, some of the locking code from the DRM
git devel repo was completely integrated..

Two problems:

1) A showstopper with the root partition on RAID1:

md: raid1 personality registered for level 1
[--snip--]
md: multipath personality registered for level -4
register_blkdev: failed to get major for mdp
[--snip--]
VFS: Cannot open root device "md1" or unknown-block(0,0)

At the moment I have no serial console attached to the box, so I had to rewrite
the messages manually.

2) On HPC nx6325 I get the following 100% of the time during the resume from
disk:

BUG: at drivers/pci/pci.c:823 pcim_enable_device()

Call Trace:

 [<ffffffff8025711e>] system_call+0x7e/0x83

Nevertheless, the system seems to be fully functional after the resume.

[I've been observing it since 2.6.20-git10 and have reported it for a couple
of times, but apparently nobody cares. :-(]

Greetings,
Rafael

Someone else reported that against mainline.  Can you please debug it a bit?

I'd suggested reverting the recent changes in there:

--- a/block/genhd.c~a
+++ a/block/genhd.c
@@ -61,14 +61,6 @@ int register_blkdev(unsigned int major, 
 	/* temporary */
 	if (major == 0) {
 		for (index = ARRAY_SIZE(major_names)-1; index > 0; index--) {
-			/*
-			 * Disallow the LANANA-assigned LOCAL/EXPERIMENTAL
-			 * majors
-			 */
-			if ((60 <= index && index <= 63) ||
-					(120 <= index && index <= 127) ||
-					(240 <= index && index <= 254))
-				continue;
 			if (major_names[index] == NULL)
 				break;
 		}
_

but I don't see how they could cause this.

This is a Tejun thing - apparently it's due to swsusp calling suspend once
and resume twice (or is it vice versa).  He'll be looking into it soon.

How did you provoke that?  modprobe rtc-cmos?

Plus, I'd guess, the old rtc driver statically linked.

What I see is a should-not-happen fault of some kind in a cleanup
path that's been tested with non-PNP rtc drivers.  A quick glance
at the code left me puzzled.  Would sleeping a second or two before
calling rtc_device_unregister() change that behavior?

FWIW, I don't see it on an SMP machine.

On non-SMP it's reproducible, eg. by doing

# echo testproc > /sys/power/disk

and

# echo disk > /sys/power/state

for 3-4 times in a row.

Probably "sync" for a couple of times in a row would be sufficient.

You're right, I should have put that somewhere under #ifdef

I've just booted OpenSUSE 10.2 with this kernel.

It may be related to preemption.  The box I'm not seeing it on runs a
non-preemptible kernel (CONFIG_PREEMPT_VOLUNTARY is set).

BTW, on the box where I'm able to reproduce it, I have

(gdb) l *__make_request+0x134
0xffffffff8034b764 is in __make_request (include/asm/processor.h:411).
406     #define cpu_has_fpu 1
407
408     #define ARCH_HAS_PREFETCH
409     static inline void prefetch(void *x)
410     {
411             asm volatile("prefetcht0 %0" :: "m" (*(unsigned long *)x));
412     }
413
414     #define ARCH_HAS_PREFETCHW 1
415     static inline void prefetchw(void *x)

So I guess x is NULL somewhere ...

The MMC_BLOCK option was accidentally lost.

For now I can only say 2.6.20 + origin.patch breaks.

However, it's a SUSE 10.1 system with gcc 4.1.0 and this may be the reason.
I'll check that tomorrow.

Yes, Rolf says this goes away when you stop using gcc-4.1.0.

I'm hoping that churning the code around like below makes things work
right.



From: Andrew Morton <akpm@linux-foundation.org>

Several people have reported failures in dynamic major device number handling
due to the recent changes in there to avoid handing out the local/experimental
majors.

Rolf reports that this is due to a gcc-4.1.0 bug.

The patch refactors that code a lot in an attempt to provoke the compiler into
behaving.

:) It may not be related though. I think that my patch avoids the
BUG_ON(!rq_mergeable(req)); in ll_rw_blk.c:2782. This looks like another
beast to me.

The code is in lookup.c:

if (oldsize) {
	int minsize = malloc_sizes[0].cs_size;

	if (!newsize || ((oldsize < newsize) && (newsize > minsize))) {
		kfree(info->lower_paths);
		info->lower_paths = NULL;
	}
}

That's the only user of malloc_sizes. It is supposed to be an optimization -
we get the smallest sized piece of memory even if we don't need all of it.
This way we don't reallocate & memcpy needlessly.

FWIW, with CONFIG_PREEMPT unset (CONFIG_PREEMPT_VOLUNTARY is set instead), I'm
unable to reproduce this problem on the box on which it is readily reproducible with
CONFIG_PREEMPT set.

Looks like reiserfs has some locking problems:

=============================================
[ INFO: possible recursive locking detected ]
2.6.20-mm2 #6
---------------------------------------------
beagled/4786 is trying to acquire lock:
 (&inode->i_mutex){--..}, at: [<ffffffff80479df9>] mutex_lock+0x19/0x20

but task is already holding lock:
 (&inode->i_mutex){--..}, at: [<ffffffff80479df9>] mutex_lock+0x19/0x20

other info that might help us debug this:

I'm not surprised...  I routinely tell people to turn it off, when 
debugging a problem.

This looks like the same I have been seeing in every release
since 2.6.18. I reported it a couple of times, and Srinivasa Ds
tried a few fixes on me during 2.6.19-rc4, but we never got to
the bottom of it.

How about exporting ksize to modules, and introduce a new function such
like this?
Of course, adding gfp_t to its parameter list make this function more generic.

void *kzrealloc(void *p, int nused, int new_sz)
{
	void *q;

	if (new_sz <= nused)
		return p;
	if (new_sz <= ksize(p)) {
		memset(p + nused, 0, new_sz - nused);
		return p;
	}

	q = kmalloc(new_sz, GFP_KERNEL);
	if (unlikely(!q))

For the time being, I included it in unionfs.git. I wouldn't mind having
this dependency disappear.

Thanks,

If you select an option, you have to ensure that the dependencies of all 
options you are select'ing are fulfilled.

This patch fixes the following compile error:

<--  snip  -->

...

inode.c:(.init.text+0x3621): undefined reference to `kernel_subsys'

<--  snip  -->

I've also removed the superfluous "default n".

urgh, no, please don't poke around in slab internals like that.

If you want to propose an extension to the slab ABI the please do so and
we'll take a look at it.

I can't say more until I've managed to understand your description, which

I agree that it is a hack.

It is intended for reallocation of a buffer. The code in lookup.c allocates
some memory, and it may have to reallocate the buffer. The code tries to
prevent some unneeded allocations by looking at what the smallest object the
slabcache gives you is.

I hope this explains it better. There's some discussion about this in the
threads by Pekka Enberg.

Problem is, it doesn't seem that we'll be merging unionfs any time soon so
we shouldn't be adding slab infrastructure on its behalf.  And I'd prefer
not to have to carry slab changes in a filesystem tree.

Although if the changes are generally ok-looking and are compact then it'd
be OK, but I do need to be alert for someone who comes along and uses that
infrastructure in an unrelated patch, which has happened before.  When I
prep the patch for an upstream merge, oops, doesn't compile any more.


So for now, it'd be best to jsut forget about the optimisation.

How useful is it, anyway?

For what it's worth, the new branch-management code also needs realloc():
right now I do a kfree/kalloc instead.  So I'm all for having a true
krealloc function.

Sounds reasonable to be weary of patches like that...

Well...

> How useful is it, anyway?

The code in lookup gets called frequently enough that I'm not sure. Whenever
one touches a file on a read-only branch, a copyup is done. This may have to
recreate the directory hierarchy leading up to the file - since the VFS
doesn't have such code, unionfs builds up a stack of all the path
components, and then it pops them off one at a time calling vfs_mkdir for
each. The stack creation is where we do this "reallocation."

Until someone merges the BSOD-for-Linux patch, I'll continue to
assume that oopsing is the wrong response to "user" mistakes.  ;)

Legacy drivers can be such a PITA.

Shoot.  OK, I'll see if I can reproduce it myself.  Is this system
using a generic CMOS RTC?  Or is HPET somehow involved?  (That old
RTC driver has HPET voodoo as well as normal RTC stuff.)

I think we can merge krealloc without unionfs. I'll whoop up a new patch 
as per Christoph's suggestions. I think at least XFS already has its own 
realloc and there might be some other open-coded users. It's not 
_changing_ the slab as much as adding new functionality that makes sense 
fron a general point of view.

The ksize exports we can add later if unionfs is to be merged.

Actually, we probably don't need it after the krealloc optimizations. I

I really like the krealloc idea. Could we useful elsewhere to extend 
objects and it is similar to the realloc() available in glibc.

Unfortunately, the userland shipped with OpenSUSE refuses to talk to the new
one (or I don't know how to make it do that).

Did your "udev" create a /dev/rtc0?  If not, /sys/class/rtc-dev/rtc0/dev
will give the right major/minor numbers.

Given a /dev/rtc0, there are two simple solutions:

  (a) ln -s /dev/rtc0 /dev/rtc
  (b) upgrade your "hwclock" to one supporting "hwclock --file /dev/rtc0",
      since that should also try rtc0 when rtc can't be opened.

I found a udev incantation "git whatchanged drivers/rtc/rtc-dev.c",
which can automate (a):

       KERNEL=="rtc0", SYMLINK+="rtc"

I'm not sure what the story is on hwclock updates, given the issue
with "util-linux" maintainership.  I sent a patch on 7-Aug-2006 to
Adrian Bunk, which appears to have been disregarded, then to Karel
Zak (for the new fork?) on 17-Nov-2006 ... but if there's been an
announcement about a new util-linux repository with that patch,
I missed it.  The busybox patch I submitted 26-Jan-2007 hasn't
yet been merged, but that's a lot more understandable.

Basically it looks like userspace is almost a year behind the kernel
support for this RTC framework.  The problematic part is that it
seems that the "util-linux" maintainership issues are preventing
that issue from getting resolved ... so for now, I usually use
workaround (a).

If your boot messages say things about HPET, that's a start.  :)
I don't really know HPET; it hasn't ever come up on any system
that I've used.  ISTR that for various reasons BIOS would hide
it on most systems, but that Linux has been working on un-hiding
that hardware so it could be used.  I'll read up on it.  (As I
implied, the source code comments leave a lot to be desired.)

The bug isn't in rtc_cmos, but that's the only driver that would currently
show the bug.  (Triggered by finding the IRQ claimed by the legacy driver,
result of a "but it should still be safe!" misconfiguration.)

The following fixes this on my 2.6.21-rc1 system; same fix should apply
to MM2.

=====================	CUT HERE
Fix an oops on the rtc_device_unregister() path by waiting until the
last moment before nulling the rtc->ops vector.  Fix some potential
oopses by having the rtc_class_open()/rtc_class_close() interface
increase the RTC's reference count while an RTC handle is available
outside the RTC framework.

Hi Andrew, all,

I appear to need the following fix to be able to build 2.6.20-mm2 on
x86_64. Without the fix, my build attempt dies on:

In file included from drivers/pci/quirks.c:532:
include/asm/io_apic.h:61: error: "MAX_IO_APICS" undeclared here (not in a function)

Not sure how nobody else was bitten by this one yet... i386 seems to
need the same so I've fixed it as well.

erk.

My problem is that I need to work out which patch in -mm broke the build so
that I can insert this patch in the appropriate position.

Can you please send the offending .config so I can do that?

Thanks.

I've bisected myself 2.6.20-mm2 instead. And the winners are:
x86_64-mm-adjust-inclusion-of-asm-fixmap_h.patch
x86_64-mm-adjust-inclusion-of-asm-vsyscall32_h.patch

The former breaks the compilation in a different way. The latter fixes
it but causes the breakage I reported originally.

Does it really matter anyway? Even in mainline,
include/asm-x86_64/io_apic.h uses MAX_IO_APICS, so it should include
the header file which defines it, that is <asm/apicdef.h>. It doesn't,
that's a bug, let's just fix it. Same for i386. So what about pushing
my patch to Linus right away?

Thanks,

Thanks Adrian.  I'd already done a lot of this locally, but I'll
double-check before posting.

Are you sure?  I thought I added this because akpm was getting compile
errors with allmodconfig.

I don't see how this could be used in any modules in 2.6.20-mm2
(and the removal didn't result in any additional errors).

The patch fixes the Oops on my Asus L5D and allows it to suspend to disk
(without it the problem is present in 2.6.21-rc1 and 2.6.21-rc2).

I think it should go into 2.6.21.

Greetings,
Rafael

Is this Problem still investigated? I got the same kernel bug a few
minutes after booting my system with 2.6.20-mm2. As a student i am not
yet as familiar with kernel programming as i want to be, but i will try,
i promise. In the meantime, i always try to test the newest mm patches,
and i have to say, this one is the first which doesent work right on my
sys since 2.6.15-mm1. Thanks, keep up the good work an please help me
with this Problem
