So this is effectively reverting c6100a4b4e3d1650deafd ("Btrfs: replace
tree->mapping with tree->private_data"), that seems to be preparatory
work for btree_inode removal. I haven't heared any news about that work
for a long time though, so if this is going to land any time soon then
we can keep it there. Otherwise, well, ack for the patch.
