When the extended attribute namespace grows to a b-tree, the leaf clusters are organized by means of 'buckets'. Each bucket is 4K in size, regardless of blocksize. Thus, a bucket may be made of more than one block. fs/ocfs2/xattr.c has a nice little abstraction to wrap this, struct ocfs2_xattr_bucket. It contains a list of buffer_heads representing these blocks, and there is even an
