Hi all,
Minor amendments to the fstests code now that we've taken FIEXCHANGE
private to XFS.
If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.
This has been running on the djcloud for months with no problems. Enjoy!
Comments and questions are, as always, welcome.
