	The end of the xfs_da_args structure has 4 unsigned char fields for true/false information on directory and attr operations using the xfs_da_args structure. The following converts these 4 into a op_flags field that uses the first 4 bits for these fields and allows expansion for future operation information (eg. case-insensitive lookup request).
