Sure, although if you run fstress in parallel ntfs3 will lock up, the
system hard, and it has at least one lockdep deadlock complaints.
It's not up to me, but personally, I'd feel better if *someone* at
Paragon Software responded to Darrrick and my queries about their
quality assurance, and/or made commitments that they would at least
*try* to fix the problems that about 5 minutes of testing using
fstests turned up trivially.

I can even give them patches and configsto make it trivially easy for
them to run fstests using KVM or GCE....
