In (standard, non-privileged) container environments the /sys/fs/cgroup mountpoint is not available. This would cause the tests to fail, as TestGetPIDLimit() tries to write to the cgroup configuration. The test will work when run as root on a privileged container or directly on a host (as Travis CI does). Setting the CEPH_CSI_RUN_ALL_TESTS environment variable to a non-empty value will cause the test to be executed. Signed-off-by: Niels de Vos <ndevos@redhat.com>
