if (ndr_desc->flush) 1) nd_region->flush = ndr_desc->flush; else 2) nd_region->flush = NULL;
When entering the "else" branch, the value of ndr_desc->flush is NULL. After replaced "NULL" with "ndr_desc->flush" at 2), we will find that it becomes the same to 1). So the above code snippet can be reduced to one statement: nd_region->flush = ndr_desc->flush; No functional change.
