selftests/mm: save and restore nr_hugepages value Save and restore nr_hugepages before changing it during the test. A test should not change system wide settings.

selftests/mm: hugetlb_reparenting_test: do not unmount Patch series "selftests/mm: Improve run_vmtests.sh", v3. In this series, I'm trying to add 3 missing tests to vm_runtests.sh which is used to run all the tests in mm suite. These tests weren't running by CIs. While enabling them and through review feedback, I've fixed some problems in tests as well. I've found more flakiness in more tests which I'll be fixing with future patches. hugetlb-read-hwpoison test is being added where it can only run with newly added "-d" (destructive) flag only. Not sure why it is failing again. So once it become stable, we can think of moving it to default set of tests if it doesn't have any side-effect to them. This patch (of 5): Do not unmount the cgroup if it wasn't mounted by the test. The earlier patch had fixed this for charge_reserved_hugetlb, but not for this test. I'm adding fixes tag to that earlier patch.

selftests/mm: fix awk usage in charge_reserved_hugetlb.sh and hugetlb_reparenting_test.sh that may cause error According to the awk manual, the -e option does not need to be specified in front of 'program' (unless you need to mix program-file). The redundant -e option can cause error when users use awk tools other than gawk (for example, mawk does not support the -e option). Error Example: awk: not an option: -e Link: https://lkml.kernel.org/r/VI1P193MB075228810591AF2FDD7D42C599C3A@VI1P193MB0752.EURP193.PROD.OUTLOOK.COM Signed-off-by: Juntong Deng <juntong.deng@outlook.com> Cc: Shuah Khan <shuah@kernel.org> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

selftests/mm: give scripts execute permission When run under run_vmtests.sh, test scripts were failing to run with "permission denied" due to the scripts not being executable. It is also annoying not to be able to directly invoke run_vmtests.sh, which is solved by giving also it the execute permission.
