How to run: - make install - make headers_install INSTALL_HDR_PATH=/usr # in case UAPI is changed - reboot - make -C tools/testing/selftests TARGETS=ublk run_test Thanks, V2: - fix one sqe allocation bug, so ublk zero copy with io_link can pass - dump log in case of error - add one more test for mkfs/mount on zero copy Ming Lei (3): selftests: ublk: add kernel selftests for ublk selftests: ublk: add file backed ublk selftests: ublk: add ublk zero copy test MAINTAINERS | 1 + tools/testing/selftests/Makefile | 1 + tools/testing/selftests/ublk/.gitignore | 3 + tools/testing/selftests/ublk/Makefile | 15 + tools/testing/selftests/ublk/config | 1 + tools/testing/selftests/ublk/kublk.c | 1679 ++++++++++++++++++ tools/testing/selftests/ublk/test_common.sh | 112 ++ tools/testing/selftests/ublk/test_loop_01.sh | 30 + tools/testing/selftests/ublk/test_loop_02.sh | 21 + tools/testing/selftests/ublk/test_loop_03.sh | 32 + tools/testing/selftests/ublk/test_loop_04.sh | 21 + tools/testing/selftests/ublk/test_null_01.sh | 18 + 12 files changed, 1934 insertions(+) create mode 100644 tools/testing/selftests/ublk/.gitignore create mode 100644 tools/testing/selftests/ublk/Makefile create mode 100644 tools/testing/selftests/ublk/config create mode 100644 tools/testing/selftests/ublk/kublk.c create mode 100755 tools/testing/selftests/ublk/test_common.sh create mode 100755 tools/testing/selftests/ublk/test_loop_01.sh create mode 100755 tools/testing/selftests/ublk/test_loop_02.sh create mode 100755 tools/testing/selftests/ublk/test_loop_03.sh create mode 100755 tools/testing/selftests/ublk/test_loop_04.sh create mode 100755 tools/testing/selftests/ublk/test_null_01.sh -- 2.47.0
