btrfs-progs: check the free space tree in btrfsck
This reuses the existing code for checking the free space cache, we just need to load the free space tree. While we do that, we check a couple of invariants on the free space tree itself. This requires pulling in some code from the kernel to exclude the super stripes. Signed-off-by: Omar Sandoval <> Signed-off-by: David Sterba <>
