ocfs2: Introduce dir lookup helper struct
Many directory manipulation calls pass around a tuple of dirent, and it's containing buffer_head. Dir indexing has a bit more state, but instead of adding yet more arguments to functions, we introduce 'struct ocfs2_dir_lookup_result'. In this patch, it simply holds the same tuple, but future patches will add more state. Signed-off-by: Mark Fasheh <mfasheh@suse.com> Acked-by: Joel Becker <joel.becker@oracle.com>wifi-calibration
