There should be ENOSPC being reported during the test but they
should all be redirected to /dev/null. Perhaps shomething wrong with
redirection?

You need to be more explicit about the test description. Does "020"
mean generic/020, xfs/020, btrfs/020, etc?

32 bit system can't use a 60TB block device or file, so this needs
a "_requires_64bit_blockdev" type of check.

various tests will fail if you don't have enough memory or address
space. Expunge them from your normal testing if it's just memory
allocation that is the problem.

xfs/136 shouldn't run your machine out of memory. If it does, then
you probably should start looking for a memory leak...
