I agree with Valdis. This is how it works.

Each filesystem has its own use-case. Like XFS is for big data, btrfs
with its COW and other features meets some specific use-cases like
facebook where they have a scenario(refer
http://lwn.net/Articles/591780/ ) where btrfs suites then perfectly.

Right.  The point I was making is that although btrfs has some *really*
nice use-cases, they are by and large places where IBM is *not* going
to engage one of their storage engineers. A "use btrfs" recommendation
is going to come from a different engineering group, and a "here's
how to tune btrfs" is probably going to come from somebody in their
Professional Services (at $200/hour and up).
