Subject: [PATCH bpf-next] selftests/bpf: fix test_dev_cgroup
Date: Mon, 22 Jan 2018 20:48:40 -0800	[thread overview]
Message-ID: <20180123044840.3467394-1-ast@kernel.org> (raw)

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.

Fixes: 37f1ba0909df ("selftests/bpf: add a test for device cgroup controller")
