fiemap is no longer the default copy implementation, so check for SEEK_DATA support instead as that's preferred. This will ensure better test coverage on systems without fiemap. * init.cfg: Replace fiemap_capable_ with seek_data_capable_. This is best supported with python 3 so prefer that. * tests/seek-data-capable: A new test script checking for SEEK_DATA support on the passed file name, called from seek_data_capable_. * tests/fiemap-capable: Remove no longer used probing script. * tests/cp/fiemap-perf.sh: Renamed to tests/cp/sparse-perf.sh * tests/cp/fiemap-2.sh: Renamed to tests/cp/sparse-2.sh * tests/cp/fiemap-extents.sh: Renamed to tests/cp/sparse-extents.sh * tests/cp/sparse-fiemap.sh: Renamed to tests/cp/sparse-extents-2.sh * tests/cp/fiemap-FMR.sh: Renamed to tests/cp/copy-FMR.sh * tests/local.mk: Reference the renamed tests.
