Since this test examines dedupe behavior, the documentation should say 'dedupe', not 'reflink'. Furthermore, the feature checks must look for working dedupe functionality, not reflink functionality.

|
# Test the convention that dedupe with length == 0 means "to the end of fileA"
|
|
# - Create a file.
|
|
# - Try to dedupe "zero" bytes (which means dedupe to EOF).
|
|
# - Check that the dedupe happened.
