The test purpose would need to be better defined, the file header says
"check out-of-space behaviour". Not really helpful.  The test script
creates a 50MB filesystem, fills it, removes the file and compares what
'df' reports. The test result can change depending eg. on the mkfs
options, if compression is enabled. So if the test fails, it does not
tell us much. I would not worry about it.
