[ Upstream commit 8e6875250a1189e0d8db8b05e18abe63c2744521 ]
The test incorrectly doing mkdir /mnt/cgroup-test-work-dirtest-bpf-based-device-cgroup instead of mkdir /mnt/cgroup-test-work-dir/test-bpf-based-device-cgroup
somehow such mkdir succeeds and new directory appears: /mnt/cgroup-test-work-dir/cgroup-test-work-dirtest-bpf-based-device-cgroup
Later cleanup via nftw("/mnt/cgroup-test-work-dir", ...); doesn't walk this directory. "rmdir /mnt/cgroup-test-work-dir" succeeds, but bpf program and dangling cgroup stays in memory. That's a separate issue on a cgroup side. For now fix the test.
