<cough> Yes, my aim was to gauge their interest in actively QAing the
driver's current problems so that it doesn't become one of the shabby
Linux filesystem drivers, like <cough>ntfs.

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.
