From: Matteo Croce <teknora...@meta.com> Add a simple test for the --reflink option. The test creates an archive with --reflink, then checks that the resulting aarchive size is multiple of 4k, then checks if the archive contains the comment records to pad the data, and finally extracts it with the --reflink option. --- tests/reflink.at | 55 ++++++++++++++++++++++++++++++++++++++++++++++ tests/testsuite.at | 3 +++ 2 files changed, 58 insertions(+) create mode 100644 tests/reflink.at
