If the devs can use this, I can provide this.
For now, the FS got even worse than that, it just hangs btrfs cleaner
processes without me doing anything, so I think they got enough data on what
is going wrong with it, although I'm not sure if it's fixed in 3.15 or not.
I'm waiting just a bit longer before destroying and rebuilding this
filesystem, hence my other questions on how to it better for next time on
the block level side.
Is anyone else using btrfs on top of dmcrypt and software raid 5?
