	In this patch, debugfs uses low-level access to walk the xattr
disk structures.  I think this is a good thing, because debugfs exists
to walk and display the low-level.
	I wish that it accessed buckets via a bucket API, but we'll do
that later.
	Also later, I'd like to see "xattr-list" and "xattr-get"
commands added.  Once libocfs2 has ocfs2_xattr_get() and
ocfs2_xattr_list(), these commands would perform that action.  Thus, the
"xattrs" commands dumps all the xattr names including the disk offset
printing, while "xattr-list" would list the names via the API and would
not display the disk structures.
	But that's all for after we land this series.
