Public bug reported:

Issue found on f/ein 5.4.0-1062, I assume it's the cause of sut-test
failure like what we see in bug 2075275

Test log:
 Running 'make run_tests -C memfd TEST_PROGS=run_hugetlbfs_test.sh TEST_GEN_PROGS='' TEST_CUSTOM_PROGS='''
 make: Entering directory '/home/ubuntu/autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/memfd'

>From the test script on Focal:
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal/tree/tools/testing/selftests/memfd/run_hugetlbfs_test.sh

There is no "HugePages_Free:" in /proc/meminfo, therefore freepgs is
empty. This is the cause of "# ./run_hugetlbfs_test.sh: line 47: [: -lt:
unary operator expected" failure. And test should bail out here.
