# Ensure that we can reflink and dedupe blocks within the same file...
|
|
# - Create a file with three distinct blocks ABB
|
|
# - Reflink block zero to the multiple-of-three blocks
|
|
# - Reflink block one to the multiple-of-five blocks
|
|
# - Dedupe block two to the multiple-of-seven blocks
|
|
# - Check that we successfully avoid deduping with holes, unwritten
|
|
# extents, and non-matches; but actually dedupe real matches.
