Howdy,

I writing slides about btrfs for an upcoming talk (at linuxcon) and I was trying to gather a list of companies that contribute code to btrfs.

What I came up with (sorted alphabetically)
Couchbase (CouchDB)
Facebook
Fujitsu
Fusion-IO
Oracle
SGI
Suse

Are there other companies I missed?

Thanks,
Marc

Which companies are using Btrfs in production?

Oh while we're at it, are there companies that can say they are using btrfs in production?

On the Gluster Listsrv a few brave souls have used it on as a distributive filesystem[1]. Here at UCI's HPC Cluster we *might* use it on a scratch filesystem ... if we upgrade to a newer kernel....

Netgear uses BTRFS as the filesystem in their refreshed ReadyNAS line. They apparently use Oracle's linux distro so I assume they're relying on them to do most of the heavy lifting as far as support BTRFS and backporting goes since they're still on 3.0! They also have raid5/6 support so they are probably running BTRFS on top of md.

Yes, and any contributions you see coming from me so far, come from NETGEAR. I've been using my gmail account because I can't make our corporate email server leave off the nasty confidentiality legal disclaimer.

We don't use Oracle's distro. Our OS is a Debian derivative, but we have pulled in lots of changes from Oracle UEK and the SUSE SLE11-SP3 kernel tree. And we do indeed run atop MD.

There are lots of contributors with the same small amout of patches contributed and are not listed there. This is first time I hear about Netgear being a contributor and it looks strange to see that name among the major contributors.

If there's demand to list all the minor contributors, then let's add a separate section, otherwise I'm going to remove the entry.

This is a sensitive PR topic that I'm normally avoiding, but in this case I don't see the amount of contributions that would qualify to the "hall of fame".

I'm always amazed when I count up the number of people and companies sending code in. There really are too many to list, but every talk I give includes a slide trying to give credit the community.

I'd be happy to see people add themselves to a "we're contributors" section if they have been part of progs or kernel releases for a year.

Code review, patch submission, and helping users on the list/irc all count.

Mmmh. So I'm not Jon Corbet who has all those fancy honed scripts + non trivial time he spends doing this by hand.

That said, my goal was not to say which company gave the most contributions and try and rank them.
Honestly, right now any company that is using btrfs and contributing to it is a great thing in my book.
I'm not even a fan of counting number of lines or frequency of patches. How do you compare someone sending easy cleanup patches vs someone who spent a month tracking down a file corruption problem no one could find nor fix, and sends a 3 line patch to fix it in the end?

But eh, I'm just one guy and and it's just my opinion :)

How about we leave that decision with Chris Mason?

For such a small community I think it would be a mistake to have arbitrary quality or quantity
thresholds for "who deserves to be on the list".

I think you should list everyone. Even if they only sent a single patch to fix a typo in a comment.
If they sent a patch, then it means they care about the code base and then they should be on the list.

Patch count itself as a metric does not work, I'm roughly calculating amount of work spent on contribution in the area of patches, testing, bugreporting, documentation, community support. For all the companies listed there is a clear record of these activies, that's what they get the credit for.

The non-company/community deserve the entry on itself, but I was not discussing community contributions.

I really like to see random people sending patches and I try to help them to get patches merged by doing reviews or commenting.

Just for the record, I certainly didn't mean that my git patch-counting example was the be-all and end-all of "contribution accounting" - it's just one metric of many; not meant to be inclusive, but might help to avoid missing people or companies who have contributed in this particular way.

Hi Marc,

If you're listing Couchbase because you noticed I'm one of their employees, then you can remove it from the list (I've never seen any couchbase mail address or other employees contributing anything to btrfs).
All my contributions are done during my personal time and by my own initiative (that's why I only use my personal gmail address for all messages to this list and patches).

As an aside, CouchDB is an Apache Software Foundation project, completely unrelated to Couchbase. It's unfortunate the company uses the term Couch for its name/products too - it confuses a lot of people
- as one of the ex-founders was the CouchDB creator and it employs (and employed more in the past) CouchDB contributors (like me). Both databases are very different at several levels: features, goals, architecture, implementation, etc.

thanks

I writing slides about btrfs for an upcoming talk (at linuxcon) and I was trying to gather a list of companies that contribute code to btrfs.

Quoted 7 lines
Quoted 5 lines

"[...] Jointly developed at Oracle, Red Hat, Fujitsu, Intel, SUSE, STRATO [...]"

Quoted 1 line

Are there other companies I missed?

The page now says "... Jointly developed at Facebook, Oracle, Red Hat .... " :D

I went a step further and made a web page to list contributors here:
https://btrfs.wiki.kernel.org/index.php/Contributors

Thanks,
Marc

So I just ran into this now. I did a quick gitdm run over the entire btrfs history in the kernel and came up with this:

Top changeset contributors by employer
Oracle 1249 (33.2%)
Fujitsu 613 (16.3%)
Red Hat 483 (12.8%)
Fusion-IO 296 (7.9%)
(None) 288 (7.6%)
Novell 203 (5.4%)
STRATO AG 152 (4.0%)
Couchbase 106 (2.8%)
(Consultant) 62 (1.6%)
(Unknown) 54 (1.4%)
Intel 48 (1.3%)
New Dream Network 36 (1.0%)
Facebook 31 (0.8%)
IBM 20 (0.5%)
FOSS Outreach Program for Women 12 (0.3%)
Google 12 (0.3%)
(Academia) 11 (0.3%)
Parallels 11 (0.3%)
HP 10 (0.3%)
Datera Inc. 5 (0.1%)

I would expect the rankings to change a bit in the near future, if those slackers at Facebook ever get it in gear...:)

Grin, Josef has taken a few weeks off to look after the newly released Josefv3.

We've got the pool of web servers on btrfs at 800 now, and soon I'm sure it'll start kicking out some fun bugs.

Once we get the btrfs tier up to 1000, I'll have a second slice of 1000 machines running 3.14 as well (or whatever the current linus rev is).

Those will be btrfs too, I expect the crash recovery code will get quite a bit of testing.

I wonder how much of this is actually due to Chris Mason changing his email address.

You can buy domain names on the open market.
You can also buy developer Emails and you get a free developer along with the Email you just bought ;-)

Most of those are really Josef, but it's the right idea.
