Note I didn't even ask for a particular percentage of passing tests, because I already know that non-Unix filesystems fail the tests that look for the more Unix-specific behaviors. I really only wanted them to tell /us/ what the baseline is. IMHO the silence from them is a lot more telling. Both generic/013 and generic/475 are basic "try to create files and read and write data to them" exercisers; failing those is a red flag. --D > I can even give them patches and configsto make it trivially easy for > them to run fstests using KVM or GCE.... > > - Ted
