Remove all the site-specific OOM messages because they duplicate
the MM subsystem generic OOM message.
Saves ~.2% (~2.5kb) of code/text in an x86 defconfig

Removing unnecessary messages saves code and text.
Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

* [Bridge] [PATCH 06/24] netfilter: Remove unnecessary OOM logging messages
@ 2011-08-29 21:17 ` Joe Perches

Alexey Kuznetsov, David S. Miller
Removing unnecessary messages saves code and text.
Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

Removing unnecessary messages saves code and text.
Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

By mine, that's for sure. It's duplicating something that the allocation
layers are already going to print.

It would be nice if you could avoid all these patches, that you dont
even read.
As I already told you in the past, __GFP_NOWARN dont print generic OOM
messages.
Its not because I told Wang Shaoyan not adding a useless "pr_err("Out of
memory\n");" in last gianfar patch, that you have to remove all
messages, with one hundred or more patches.
If I remember well, you even disagreed at that time.
Furthermore, a failed vmalloc() is not guaranteed to emit an OOM
message, is it ?

It currently displays a message without context :
vmap allocation for size XXXXXX failed: use vmalloc=<size> to increase
size.
So we dont know which part of the kernel asked this allocation.
Please dont remove existing error messages after failed vmalloc() calls.

I have a question about that. Are the dprints going to show the stack backtrace?
Otherwise how can I see which exact allocation failed and was not properly handled?
If yes above? then I'm not sure I like it either, because am I'll be getting a full
stack backtrace for every failed allocation?
But I might like it if I try. How do I turn on allocation failures prints?
Can I filter out to print only GFP_KERNEL failures and or other GFP combinations?
Thanks

Yes, OOMs give full stack backtraces.

They've been doing this for years, so obviously they haven't bothered you
enough to care up to this point.
All of this pushback is pure uneducated noise, please stop blocking progress
with poorly informed objections.

They've been doing this for years, so obviously they haven't bothered you
enough to care up to this point.
All of this pushback is pure uneducated noise, please stop blocking progress
with poorly informed objections.

Right. If every GFP_ATOMIC or GFP_NOWAIT is going to print out stack traces, then we're heading for absolute insanity. If not, then the existing dprintk()s make a lot more sense, 'cos they are turned on only when the administrator notices a problem, and is trying to debug it.

Indeed.
Joe, these vmalloc() and also the __GFP_NOWARN cases will need to be
attended to and this series resubmitted as such.
Thanks.

Not really that much of an impact, but yes, I agree it just swamps
syslog with duplicate messages... It was more debug code than
anything else originally. Beats me why it is logged as KERN_ERR or
KERN_CRIT, being out of buffers is not really fatal or even
unusual.

I can see that slub.c has the slab_out_of_memory() function that
(although ratelimited) warns you if the allocation failed. However I
can't find any equivalent for slab.c or slob.c.

OK That would explain why I never saw it in my debugging. For some reason
I'm always using slab.

I didn't notice those had GFP_NOWARN.

No, what I said was that it'd be better to get agreement
to delete them before deleting them.
https://lkml.org/lkml/2011/8/9/379
So I submitted an RFC and cc'd you.
You did not reply.

Doesn't seem to be, perhaps it should be
when __GFP_NOWARN is not set...

I didn't notice those had GFP_NOWARN.

No, what I said was that it'd be better to get agreement
to delete them before deleting them.

So I submitted an RFC and cc'd you.
You did not reply.

Doesn't seem to be, perhaps it should be
when __GFP_NOWARN is not set...

It doesn't matter to me one way or another.
If you pick this one up, when I redo these
to separate vmalloc from the the other alloc
cases, I'll won't send netfilter again.

I'm happy with subsystem folks taking things in if they want, the

No worries.
Andrew Morton picked up a patch I posted that
changes vmalloc to be similar to kmalloc when
the pointer returned is NULL (OOM). It now
uses dump_stack for those cases.
https://patchwork.kernel.org/patch/1114682/
I'll keep all the current vmalloc failure messages
for now and resubmit in a day or two this series
with acks. Not batman or netfilter though as they
were picked up by their maintainers.
A month or two after the vmalloc patch hits
mainline and/or wider testing, and it's deemed
acceptable, removing vmalloc site specific OOM
messages should be appropriate.
Anyone object?
I plan on submitting drivers/net OOM removals
next week.

I have rescued this patch and put into this tree:
http://1984.lsi.us.es/git/?p=net-next/.git;a=shortlog;h=refs/heads/nf-next
At that time (kernel.org problems), we had no public tree and Patrick
temporarily stored in his internal tree.
