This read-ahead needs parent node block, so nilfs_btree_readahead_info structure is added to pass the information that __nilfs_btree_get_block() needs. This also replaces the previous nilfs_btree_get_block() implementation with a wrapper function of __nilfs_btree_get_block(). Signed-off-by: Ryusuke Konishi --- Reading git-diff-tree failed
