Check hugetlbfs support before starting tests in run_hugetlbfs_test.sh. Otherwise on a system that does not support hugetlbfs the free huge pages availability check will fail with: ./run_hugetlbfs_test.sh: line 47: [: -lt: unary operator expected ./run_hugetlbfs_test.sh: line 60: 12577 Aborted (core dumped) ./memfd_test hugetlbfs Aborted (core dumped)
And it will left a fuse_mnt process behind, which may cause some unexpected issues. Patch tested with a kernel that does not have hugetlbfs support enabled and the test was skipped as expected.
