The user land progs needs a simple way to read

As of now btrfs-devlist uses this ioctl.
In the long run this ioctl would help to optimize
some part of btrfs-progs, mainly the current
btrfs filesystem show
Just thinking out loud here, really, but can we export this
information in /sys instead, rather than adding yet more ioctls?
I was more inclined towards (live) memory dump. But I need to fix
btrfs-progs as well so ioctl.
