Stefan and Jan pointed out a problem with this patch that would result
in read_extent_buffer calls that read beyond the leaf size when an old
root item is found at the end of a leaf. I pushed a fix to github that
tries to replace read_extent_buffer calls with a new helper function
(btrfs_read_root_item). The patch also adds a __le64 reserved[8] field
to the root_item struct, which means that when you apply that fix all
your extra information in the root items will get lost on next mount.

As already said in the cover letter, I will not send patches to the
list before it's worth for version 2. Such fixes are only found in my
git repo and will later be squashed together for v2.
