What are the linux kernel versions incompatibilities with btrfs?

What are the linux kernel versions incompatibilities with btrfs?

[Brent Millare]

I read that usage of a btrfs volume with a newer kernel can render it
unreadable when that same volume is used with an older kernel. I have
a mobile storage device that will be used by different linux
distributions and kernels. What are the kernel version
incompatibilities I might have to worry about? The machines I will use
have kernel versions 3.2.0, 3.5.0, and higher.

Hi,

I can't give you a specific answer to your question. But because btrfs
is still under heavy development you shouldn't use it with those old
kernels at all in my oppinion. You should never be more than one
version away from the current stable kernel.

Regards,
Felix
