Refactor every test in the entire test suite to use the new boilerplate functions. This also migrates all the test group information into the test files. This patch has been autogenerated via the command: ./tools/convert-group btrfs ceph cifs ext4 f2fs generic nfs ocfs2 overlay perf shared udf xfs Signed-off-by: Darrick J.

# different mount points of the same filesystem.

# For both situations, these actions are executed:

# - Copy a file with the reflink=auto option.

# A normal copy should be created.
