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.

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.
