When an ocfs2 extended attribute is large enough to require its own
allocation tree, we root it with an ocfs2_xattr_value_root. However,
these roots can be a part of inodes, xattr blocks, or xattr buckets.
Thus, they need a different journal access function for each container.
We wrap the bh, its journal access function, and the value root (xv) in
a structure called ocfs2_xattr_valu_buf. This is a package that can
be passed around. In this first pass, we simply pass it to the
extent tree code.
