    That's true.

    However, if Oracle makes a binary release of BTRFS-derived code,
    they must
    release the source as well; BTRFS is under the GPL.


BTRFS can be under any license they want, they own the code. There's absolutely nothing preventing them from dual-licensing it.

    So, if they're going to use it in any way as a product, they have to
    release the source.  If they want to use it just internally they
    can do
    anything they want, of course.


No, no they don't. You're under the misconception that they no longer own the code just because they released a copy as GPL. That is not true. Anyone ELSE who uses the GPL code must release modifications if they wish to distribute it due to the GPL. The original author is free to license the code as many times under as many conditions as they like, and release or not release subsequent changes they make to their own code.

I absolutely guarantee Oracle can and likely already has dual-licensed BTRFS.
No.. talk to Chris Mason.. it depends on the linux kernel too much already to be available under anything, but GPLv2
