Waiman Long e9737301f0 selftests/vm: make charge_reserved_hugetlb.sh work with existing cgroup setting ... [ Upstream commit 209376ed2a ] The hugetlb cgroup reservation test charge_reserved_hugetlb.sh assume that no cgroup filesystems are mounted before running the test. That is not true in many cases. As a result, the test fails to run. Fix that by querying the current cgroup mount setting and using the existing cgroup setup instead before attempting to freshly mount a cgroup filesystem. Similar change is also made for hugetlb_reparenting_test.sh as well, though it still has problem if cgroup v2 isn't used. The patched test scripts were run on a centos 8 based system to verify that they ran properly.
