Libra btrfs and my kobo

I am a linux guy and I love two things: my Kobo Libra and btrfs.

So, I want to format the data partition of my Libra btrfs and use lzo compression.

My question, does the Kobo kernel include btrfs modules? I don't need the userspace btrfs-progs as I will be doing all the admin work from my Arch laptop. I just need the FS to be in the kernel.

Without giving me the old btrfs warnings (it is quite stable), are there any tips or advice to this? What about fstab? I'm told Kobo uses something different.

Thanks.
