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).
There is also a bit of EOL whitespace cleanup too.
