2.6.3-mm3

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.3/2.6.3-mm2/


- Added Roman's HFS rewrite and HFS+ filesystem implementation

- Device Mapper update.  This adds support for a multipath target and seems
  fairly significant.

- Big s390 update.  This includes rework against net devices, block devices
  and sysfs interfaces.   Please Cc Martin Schwidefsky on review comments ;)

- A fairly large update to the ide-scsi error handling.  If you use
  ide-scsi, please beat on this.

- A patch to the NFS client which teaches NFS to play nicely with the
  VM/VFS writer throttling framework.  Should improve interactivity
  and overall balancing niceness when performing heavy NFS write activity.

- Some VM work against slab shrinking and interzone balancing.  Relevant
  to highmem machines.

- m68k and ppc64 updates

This still doesn't shrink slab correctly on highmem machines
because you dropped my patch :(

A better way, IMO, is use mine instead of shrink_slab-for-all-zones.patch

Your other VM patches look good though.

First, one needs to define "correctly".

Certainly, it is not "solves the alleged updatedb problem".

The design behind the slab shrinking is to reclaim slab in response to
memory demand.  Not in response to lowmem demand.  With all the scaling,
accounting-for-seeks-and-locality, etc.

No, I think this is a non-problem.

That should come out in the wash with my patch anyway, because
it causes lowmem LRU pressure to assert a *lot* more slab pressure.
So highmem pressure should cause a similar amount of slab pressure
with either patch, it just comes about in different ways.

But allocations from lowmem will not shrink the slab nearly enough
with your patch because it shrinks by a percent of all pages.

Adding the HBA API ioctl crap to zfcp is not acceptable, the qlogic ioctls
already were shot down for the same reason.

Btw, please send scsi patch to linux-scsi please.

That is the wrong design. That is basically just circumventing
zone balancing, and it shows because you don't balance slab vs
lowmem properly.

Lowmem pagecache vs highmem pagecache should be balanced correctly?
I think it is with your other patches.

Lowmem pagecache vs slab should be balanced correctly with my patch.

Therefore highmem vs slab will be balanced correctly.

Is that a good proof?

Well no, because you can construct a similar "proof" for your
patch because I assume balancing between zones is a two way
operation :P. Actually, lowmem pressure does not assert highmem
pressure which is the point where your balancing fails.

Humph. OK you're right. The above is of course right when all
else is equal, however slab can only be allocated from lowmem
while pagecache can come from anywhere.

So if you have 500MB of slab and 100MB of cache in lowmem, but
10000MB cache in highmem, lowmem pressure should be shrinking
more cache than slab.

I wouldna spotted that in a million years.  That all_zones_ok code was a
bitch to test and really needs retesting.

We used to have <= in there actually:

		to_reclaim = zone->pages_high-zone->free_pages;
		if (to_reclaim <= 0)
			continue;

We've never clearly defined whether pages_high == free_pages means the zone
is under limits.  According to __alloc_pages() it means that the zone is
not under limits, so you've fixed two bugs there.

all_zones_ok is actually now the only way you can really stop
scanning (yes, you eventually run out of priority).

FWIW 2.6.3-mm3 with the above fix right now seems to behave much
better in my non-contrived cases than previous kernels I've tested
with.

Sigh.  There is absolutely nothing wrong with having a large slab cache. 
And there is nothing necessarily right about having a small one.

Sorry, but your comment is information-free.

Unless the slab contains useful data (ie. dentries that will actually
be accessed is some useful amount of time) then arguably those pages
are better used for the page-cache.

> And there is nothing necessarily right about having a small one.

Oh, I'm not claiming one is more right than the other.  The issue for
me is updatedb or even bk clone a few times will cause the slab to
swell with dentries and related contents that never seems to shrink
without forcing swapping.

> Sorry, but your comment is information-free.

I just notice I'm getting debugging output (call traces) for page
allocation failures which I've not seem before.  I was getting these
(swapper: page allocation failure. order:2, mode:0x20) after beating
things to see how bad things will get for Nick.

In this case slab is consuming so much low memory we're getting
allocation failures which was making networking choppy.

Order *two*?  That's four physically contiguous pages.  We haven't got a
snowball's chance of satisfying an order-2 GFP_ATOMIC allocation for
networking.

What's the call backtrace on these failures?

Could it be that the lower zone protection stuff simply means
that Chris's system only ever allocates page cache and anonymous
memory from his 600 MB highmem, leaving the 900 MB lowmem for
the slab cache to roam freely ?

I guess highmem allocations really should put some pressure on
lowmem, even when there is enough lowmem free, because otherwise
you end up effectively not using half of the memory on 1.5-2 GB
systems for paging ...

Hi,

I have 2.6.3 on the 1.5GB RAM server that started the "large slab" thread.

Which patches should I apply from -mm to test for improvements?

What about Nick's fix up patch for the two patches above?  Should I

Just apply the mm3 rollup patch.

Probably not.  If they apply ten they'll work.

The lower-zone protection code will only preserve an extra megabyte or so
of the normal zone in response to __GFP_HIGHMEM allocations, so it won't be
coming into play here.

I'd prefer to replace the lower-zone/incremental-min code with 2.4's
watermark code.  It's pretty much equivalent, but makes the calculations
once-only and it is easier to observe and understand its effects.  But
there's too much work going on in there to make this change at present.

Yup.  With the current -mm patches the reclaim rate from lowmem and highmem
is nicely proportional to each zone's size for pagecache-heavy workloads. 
For lowmem-intensive workloads the reclaim rate from lowmem is higher, as
one would expect.  It seems to be working OK now.

OK, that should do the trick.

2.6.3-mm3 hangs on boot x440 (scsi?)

[john stultz]

[-- Attachment #1: Type: text/plain, Size: 737 bytes --]

Andrew,
	Booting 2.6.3-mm3 on an x440 hangs the box during the SCSI probe after
the following:
 
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
        <Adaptec aic7899 Ultra160 SCSI adapter>                 
        aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs
                                                                

I went back to 2.6.3-mm1 (as it was a smaller diff) and the problem was
there as well. 

The problem is not seen using 2.6.3-bk.current

Additionally the problem does not occur on an x445 (which uses
MPT-Fusion, rather then AIC7xxx) w/ -mm1 or -mm3.

Attached is the boot log and .config (from -mm1).

Let me know if there is any additional  debug info you'd like.

thanks
-john

Could you try reverting aic7xxx-deadlock-fix.patch?  Also, add
initcall_debug to the boot command just so we know we aren't blaming the
wrong thing.

Apart from that, gosh.  Maybe you could add just linus.patch and
bk-scsi.patch, see if that hangs too?  Or just test the latest linus tree -
the scsi changes were merged this morning.  Thanks.

[PATCH 2.6.3-mm3] serialize_writeback_fdatawait patch

[Daniel McNeil]

[-- Attachment #1: Type: text/plain, Size: 634 bytes --]

Andrew,

This patch moves the serializing of writebacks up one level to before
where the dirty_pages are moved to the io_pages list.  This prevents
writebacks from missing any pages that are moved back to the
dirty list by an SYNC_NONE writeback.  I have not seen this race in
testing -- just by looking at the code.  It also skips the serialization
for blockdevs.

Also this patch changes filemap_fdatawrite() to leave the page on the
locked_pages list until the i/o has finished.  This prevents
parallel filemap_fdatawait()s from missing a page that should be
waited on.  I have not seen this in testing, either.

Thoughts?

Daniel

I was suspecting that patch, unfortunately reverting it doesn't seem to
help.

Here's the initcall_debug output:

ide-floppy driver 0.99.newide

The bk.current that I tested and worked was from about two hours ago.
But I'll spin it again as 4 new changesets have shown up.

hm, OK.  I've converted all the down_read_trylock() things into a sinple
down_read(), to address the pdflush-busywait problem which Hugh identified.

This does mean that pdflush can get blocked by ongoing sync activity but
that's probably insignificant and we have per-spindle pdflush collision
avoidance which will help a bit.

Call me lazy, but could you please work out the ranking of wb_rwsem with
respect to the other VFS locks, update the locking documentation in
mm/filemap.c and make sure that we're actually adhering to it?  Thanks.

Bah.  No sysrq-t output?

If you could send me the .config I'll see if I can make it happen on test
box #47.

I have a dual CPU server that won't boot 2.6.3-mm3.  It will however 
boot vanilla 2.6.3.

Right after is says "uncompressing kernel" and "booting" it hangs.

Any patches I should try reverting?  I know it uses aic7xxx, but it 
doesn't even get to that point.  Does ACPI start that early?

Please triple-check the .config, then boot with

	earlyprintk=vga

or set up a serial console and boot with

	earlyprintk=serial[,ttySn[,baudrate]]

Brown paper bag time.

I tried booting an Athlon compiled kernel on a PIII. :-/

Re: 2.6.3-mm3 sometimes freeze on "sync"

[Helge Hafting]

2.6.3-mm3 (and 2.6.3-mm1) occationally freeze on "sync".
They will run fine for several days, but if I do a sync
they might freeze completely and sysrq+B is the only action
that gets any response after that.  The mouse stops, the
x clock stops, and so on.

I only saw this once in mm1, and thought it might be some
glitch.  But it have happened several times with mm3,
so I'm reporting it.  It even hapopened when I ran sync
immediately after boot+login (in X) just to test.

I use the ext2 filesystem on two IDE drives.  The
root fs is ext2 on a RAID-1 on the same two drives.
I also mount nfs, but no nfs was mounted when I did
the "sync after boot+login" test.

This is the IDE controller, from lspci:
00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE]
I also have proc, tmpfs, devpts and sysfs mounted.

The machine is single-cpu, the kernel is compiled without
preempt and with register arguments and frame pointer,
using gcc 3.3.3 from debian testing.

There obviously were no logs after this freeze.

I ended up having to do that. :-/

They won't apply in the order as listed in the -mm3 series file. :(

I'm running 2.6.3-mm3-486-fazok (nick's patch), and it has improved my 
slab usage greatly.  It was averaging 500MB-700MB slab.  Now slab is 
~230MB, and page cache is ~700MB

See:
http://www.matchmail.com/stats/lrrd/matchmail.com/srv-lnx2600.matchmail.com-memory.html

Is there any way I can get the VM patches against 2.6.3?  I'm not 
comfortable with running -mm3 on this production server, especially 
seeing the "sync hang" bug.

Thanks,

Mike

alt-sysreq didn't seem to work, but the keyboard seemed dead (no
numlock,etc). Might be the KVM switch causing trouble, though.

Here's the .config again.

The other thing we could do is add a wbc->encountered_congestion = 1
if the down_read_trylock() fails and then check for that to prevent
the busywait problem.

That is a much better sounding ratio. Of course that doesn't mean much
if performance is worse. Slab might be getting reclaimed a little bit
too hard vs pagecache now.

Well your server wasn't going too badly with 2.6.3, wasn't it? Might
as well just wait for them to get into the the tree.

sorry for not following this thread, but where do I find the mm3 rollup patch 
this thread is talking about? akpm's directory does not contain it, or I am 
blind b/c it isn't named like that or similar ;>

It's just the regular ~2MB bz2 file you normally get (ie, it's not 
"split-out" like in the directory where all patches are seperate...)

I'll let you know.  My graphs are looking better, except for one 
instance of Xvnc (for one user -- I'm still tracking that one down) 
hitting a memory grabbing loop that made me kill it.

I might as well take out the third 512MB DIMM in that machine then...

Any chance you could post a VM patch roll-up against 2.6.3 for little 
ole me?

Try to get /proc/meminfo and a sysrq + T trace if something like
this happens.

It is a bit easier said than done as you might have seen :P And
I'm laz^W^W I happen to not agree with one of Andrew's patches,
so it would go against all my principles ;)

IMO, shrink_slab-for-all-zones.patch and zone-balancing-fix.patch
should be all you need although they won't shrink the slab as
much as mm3. They should be pretty easy to port by hand.

I'll do that next time.

When did /proc/sysrq-trigger get in the kernel?  forgot about that at 
the time :(

OK, I'll give that a try.

Is the attached patch the latest version of your alternative patch 
instead of shrink_slab-for-all-zones.patch?

Yes that looks like it. I am actually starting to like this patch
again now that lowmem is being properly scanned as a result of
highmem scanning.

But it should be functionally very similar to just scanning slab
on highmem pressure like -mm3 does.

That's what zone-balancing-fix.patch does, right?

Hmm well no, it still reclaims slab too hard. I just forgot

Yes... but actually the kswapd path needs something similar.
That would be the batching patch, but with a scanning value
derived from the current size of the zone's lrus.

I'd just stick with 2.6.3 for now :)

So, you think vm-shrink-slab-lowmem.patch shrinks slab too much, or 
Andrew's patch (IIRC, those comments were for Andrew's patch...)?

Hmm, do you think I'd get more slab shrinking with 2.6.3 + 
zone-balancing-fix.patch?

Not really because you shouldn't be hitting the direct reclaim
path. shrink_slab-for-all-zones.patch will help more though.

Won't Andrew's patch scan/shrink the slab more if there is more highmem 
than lowmem?

Sorry, I meant "shrink slab more than 2.6.3 with 2.6.3 + 
zone-balancing-fix.patch".

Since the zones are more balanced, there should be more lowmem scanning 
going on...

This seems to work for me.  I've booted 2.6.3-mm3 with this
patch.  I ran some syncs, then forced the machine to
swap with a big tar and ran some more syncs.  It works.

Is it also in mm4?

Problem patch is expanded-pci-config-space.patch.
x440 can not enable acpi by dmi_scan.
expanded-pci-config-space.patch need acpi support.
So, kernel can not get x440's xAPIC interrupt.

Wow, thanks for that analysis Go! I'll test it here to confirm. 

The acpi dmi blacklist entry for the x440 slipped in from United Linux's
2.4 kernel (where there were ACPI issues initially), and I don't believe
it is necessary in 2.6. I've got a patch that reverts that change, but I
want to do more testing first.

Yep, I've confirmed that backing out the expanded-pci-config-space patch
solves it. Thanks again, Go, for hunting that down! 

Matthew, any ideas why the patch fails if the system has an ACPI
blacklist entry?

Hrm.  I was just asked to break out some of the ACPI code rearrangement
from the rest of the patch.  Can you try this patch instead of the
expanded-pci-config-space.patch and tell me whether it continues to fail
for you?

I don't understand why it should make a difference though.  It looks
to me like the current code will also fail to call the HPET code if the
bios is blacklisted.

right now, but I'll happily test any patches you might think will help.

Actually, I took a second to actually look at that patch and I realized
it was just the ACPI changes, rather then just the PCI changes. 

So yes, it seems that the patch narrows down the issue to just the ACPI
changes, which isn't so unfortunate!

That chunk shouldn't drop the "if (acpi_disabled ..." bit.
Adding that check back in fixes it for me.

Just posted in reply to someone else ont he list, but I'm runnign -mm3
with the patch and seeing hangs after mkfs'ing ext3 fs'es on HP
servers with the cciss-driver; roughly 50% chance of it happening on
"umount /dir && mke2fs -j -L /dir /dev/cciss/c0d0p5 && mount /dir".

Never mind, I was brain dead at the time.

This one should be better.

[-- Attachment #1: Type: text/plain, Size: 559 bytes --]

Andrew, 
	I swear, I'll move up to -mm4 soon, but I've got one more issue w/
-mm3. 

When running -mm3 (plus the one-line fix to the expanded-pci-config
patch) to on an x440  w/ 4G enabled, the tg3 driver cannot find my
network card. 

When booting I get:
tg3.c:v2.7 (February 17, 2004)                
tg3: Cannot map device registers, aborting.
tg3: probe of 0000:01:04.0 failed with error -12

Otherwise the system seems to come up fine. 

Disabling CONFIG_ACPI (or CONFIG_X86_4G) makes the problem go away.

Boot log and .config attached. 

thanks
-john

Beats me.  Maybe acpi is returning some monstrous reosurce length and we're
running out of kernel virtual space only with the 4g split?

'twould be appreciated if you could stick a few printk's in there and work
out what's happening please.  Check out the pci space base address and
length with and without ACPI?

The base address and length are the same either way, instead its
__ioremap that's failing at "if(!PageReserved(page))"[ioremap.c:142].

I've also narrowed down the issue to only occur w/ (CONFIG_X86_4G=y &&
CONFIG_NUMA=y) so it looks like its a propblem w/ 4G and discontigmem
together. 

I've also finally moved to -mm4 and reproduced the problem there.

Martin: Any ideas?

Can you dump out all of the variables in the 
	if (phys_addr < virt_to_phys(high_memory)) {
	...
statement, plus the arguments that ioremap() is getting?

Evidently, it's OK if highmem pages aren't PageReserved(), and I'm
starting to wonder if you've done something rare, like spanned the
highmem boundary with your ioremap().  

We do some weird stuff with that highmem boundary when NUMA is on,
because we remap a bunch of mem_map[] in that area to get it local on
NUMA nodes which might be causing something unexpected.  Take a look and
see if any of the variables that __ioremap() is using correspond to
those that remap_numa_kva() is playing with (from your boot log):
node 0 will remap to vaddr f8000000 - f8000000
node 1 will remap to vaddr f5600000 - f8000000
High memory starts at vaddr f8000000    

It's just a guess.

Darren and I worked out that CONFIG_SCHED_SMT seems to be causing problems
in -mjb at least ... you might try turning that off for -mm, and see if 
that helps. Meanwhile, I'll try seeing if any of the updated sched stuff
in -mm works for me ;-)
