enable bcache in kernel?

[Stan Hoeppner]

Is bcache available in 3.4.103?

Regardless of the answer to the above, how is bcache enabled in the
kernel? .config? Doc reference please. The bcache website simply says
"now in mainline" without stating the source filename or anything actually
helpful about including it in a custom kernel.

Please reply-all.

Thanks.

Stan

I believe it went in around 3.10 but I wouldn't use it for anything
in production until at least 3.12.x
