[Jesper Juhl]

Hi,

We can avoid doing a memset in swap_cgroup_swapon() by using vzalloc().

Can we make a grep script to walk all files to find vzalloc usage like this?
No need to send patch mail one by one like this.

There's an existing cocci kmalloc/memset script.

Perhaps this is good enough?

cp scripts/coccinelle/api/alloc/kzalloc-simple.cocci scripts/coccinelle/api/alloc/vzalloc-simple.cocci
sed -i -e 's/kmalloc/vmalloc/g' -e 's/kzalloc/vzalloc/g' scripts/coccinelle/api/alloc/vzalloc-simple.cocci

I have it in

Not sure if that is the same script but certainly a good start. Try it and
see if it catches all the locations that you know of?

I'm aware of coccinelle, but I've never used it and it looks like it'll 
take more than just a few hours to learn, so I'm sticking with 
bash+egrep+manual inspection for now until I get a bit more time on my 
hands to learn coccinelle/spatch.

I assume that not using spatch is not going to be an obstacle to patches 
such as this one getting merged...?

[PATCH 00/49] Use vzalloc not vmalloc/kmemset

[Joe Perches]

Converted vmalloc/memset and vmalloc_node/memset to
vzalloc or vzalloc_node using a cocci script and some editing

Reduces text a little bit.

Compiled x86 only.

There are still vmalloc_32 with memset calls still around.

Broken out to multiple patches to cc appropriate maintainers.

[PATCH 00/49] Use vzalloc not vmalloc/kmemset

[Joe Perches]

Converted vmalloc/memset and vmalloc_node/memset to
vzalloc or vzalloc_node using a cocci script and some editing

Reduces text a little bit.

Compiled x86 only.

There are still vmalloc_32 with memset calls still around.

Broken out to multiple patches to cc appropriate maintainers.

[PATCH 00/49] Use vzalloc not vmalloc/kmemset

[Joe Perches]

Converted vmalloc/memset and vmalloc_node/memset to
vzalloc or vzalloc_node using a cocci script and some editing

Reduces text a little bit.

Compiled x86 only.

There are still vmalloc_32 with memset calls still around.

Broken out to multiple patches to cc appropriate maintainers.

[PATCH 00/49] Use vzalloc not vmalloc/kmemset

[Joe Perches]

Converted vmalloc/memset and vmalloc_node/memset to
vzalloc or vzalloc_node using a cocci script and some editing

Reduces text a little bit.

Compiled x86 only.

There are still vmalloc_32 with memset calls still around.

Broken out to multiple patches to cc appropriate maintainers.

[PATCH 00/49] Use vzalloc not vmalloc/kmemset

[Joe Perches]

Converted vmalloc/memset and vmalloc_node/memset to
vzalloc or vzalloc_node using a cocci script and some editing

Reduces text a little bit.

Compiled x86 only.

There are still vmalloc_32 with memset calls still around.

Broken out to multiple patches to cc appropriate maintainers.

You may as well move the second s_flex_groups == NULL check inside the first one:

	if (sbi->s_flex_groups == NULL) {
		sbi->s_flex_groups = vzalloc(size);
		if (sbi->s_flex_groups == NULL) {
			ext4_msg(sb, KERN_ERR, "not enough memory for "
				 "%u flex groups", flex_group_count);
			goto failed;
		}
	}

[Joe Perches]

Signed-off-by: Joe Perches <joe@perches.com>

differences from V1:
Andreas Dilger requested a block be moved so that
sbi->s_flex_groups isn't tested for NULL twice.
Also coalesced a ext4_msg printk format.

So many 'vzalloc' patches for net tree... 

I had _one_ patch, waiting that David actually had vzalloc() in its tree
before sending it.

Given Jesper Juhl was doing this work, could you please take another
one, please ?

For example, explaining him how to use other tools than "bash+egrep
+manual inspection" as he mentioned in a previous mail.

Really Joe, your behavior should be smarter than that.

Thanks

Fine by me, use yours.

Jesper Juhl was both pointed at the cocci docs and
given a cocci script.  He said he'd investigate it
when he could.  I trust he will get to it.

I think that for this sort of patchset, grep and
manual inspection works just as well as spatch
and likely better because a simple cocci script
doesn't transform code like:

	if (size > PAGE_SIZE)
		ptr = vmalloc(size);
	else
		ptr = kmalloc(size, GFP);
	if (ptr)
		memset(ptr, 0, size);

I did say in the 00 cover that this was broken up
just to cc the maintainers of each block.

I also think a single rolled-up single patch is good.

I believe Jiri Kosina can easily apply all these
individual patches as a single patch if he chooses.

I dont care at all, only to say that David tree was not ready yet.

Yes, yet you posted patches, knowing he was working on the _same_
subject.

I remember other occurrences of such behavior.

I find this behavior very unfriendly, time consuming, and not useful.

We try to work together, to increase our common knowledge, not to throw
a bunch of patches "just because I know better than you"

And I will get to look at cocci and spatch, they are definately tools that 
I want in my arsenal.

To be completely honest, I did get the feeling that the task I'd set for 
myself and was having fun doing in the little spare time I have got 
hijacked and I did waste about an hour and a half doing a few more 
cleanups before I saw the patchset on lkml.

But on the other hand, the most important thing is that it gets done, not 
who ends up doing it - especially since it's such a trivial cleanup, so I 
choose to see it as my initial patches just getting the ball rolling.

It would have been nice with at least an email along the lines of "I 
know how we can do all those patches in a jiffy, mind if I just go along 
and do that?", but I'll live. There's plenty of other stuff to do :-)

I will, after this settles a little bit (the same for the WARN series). 
I prefer waiting a bit before applying your patches usually. 

First to see what lands in linux-next through maintainer's trees, second 
to gather Acks.

I think that's the right way to do these
sorts of trivial changes too.

Individual patches cc'd to maintainers for
feedback, improvement, acks or to be directly
applied to their trees, followed by a longish
delay before any unapplied patches are taken
up as a single patch by your trivial queue.

Thanks for doing that work Jiri.

Thanks.  No worries.

fyi: the kvm git isn't in MAINTAINERS.

Perhaps something like this is appropriate

I have it in
/usr/share/doc/coccinelle/examples/janitorings/kzalloc-orig.cocci.gz

(Ubuntu coccinelle package)

Not sure if that is the same script but certainly a good start. Try it and
see if it catches all the locations that you know of?

There's an existing cocci kmalloc/memset script.

Perhaps this is good enough?

cp scripts/coccinelle/api/alloc/kzalloc-simple.cocci scripts/coccinelle/api/alloc/vzalloc-simple.cocci
sed -i -e 's/kmalloc/vmalloc/g' -e 's/kzalloc/vzalloc/g' scripts/coccinelle/api/alloc/vzalloc-simple.cocci
