NFSv4.2 supports reflink but does not support FIBMAP nor FIEMAP. These 4 tests about file content can pass on NFSv4.2, but filefrag complaints : +/mnt/testarea/scratch/test-542/file2: FIBMAP unsupported which is breaking golden output.

# Ensuring that reflinking works when the destination range covers multiple
|
|
# extents, some unwritten, some not:
|
|
#
|
|
# - Create a file with the following repeating sequence of blocks:
|
|
# 1. reflinked
|
|
# 2. unwritten
|
|
# 3. hole
|
|
# 4. regular block
|
|
# 5. delalloc
|
|
# - reflink across the halfway mark, starting with the unwritten extent.
|
|
# - Check that the files are now different where we say they're different.
