Split normal memfd and hugetlbfs tests to improve the test reporting. Remove run_fuse_test.sh and memfd_test from run_tests.sh and add them to the Makefile. Add memfd_test to TEST_GEN_PROGS to be run separately. Rename run_tests.sh to run_hugetlbfs_test.sh Add run_fuse_test.sh and run_hugetlbfs_test.sh to TEST_PROGS The report for non-root run wth this change is: TAP version 13 selftests: memfd: memfd_test ======================================== memfd: CREATE memfd: BASIC memfd: SEAL-WRITE memfd: SEAL-SHRINK memfd: SEAL-GROW memfd: SEAL-RESIZE memfd: SHARE-DUP memfd: SHARE-MMAP memfd: SHARE-OPEN memfd: SHARE-FORK memfd: SHARE-DUP (shared file-table) memfd: SHARE-MMAP (shared file-table) memfd: SHARE-OPEN (shared file-table) memfd: SHARE-FORK (shared file-table) memfd: DONE ok 1..1 selftests: memfd: memfd_test [PASS] selftests: memfd: run_fuse_test.sh ======================================== opening: ./mnt/memfd fuse: DONE ok 1..2 selftests: memfd: run_fuse_test.sh [PASS] selftests: memfd: run_hugetlbfs_test.sh ======================================== Please run memfd with hugetlbfs test as root not ok 1..3 selftests: memfd: run_hugetlbfs_test.sh [SKIP] Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org> Reviewed-by: Mike Kravetz <mike.kravetz@oracle.com> Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
