Unfortunately this test needs to be modified to work with the final agreed upon
method for switching DAX, patch below. Feel free to squash it into this patch
for v3.
There are more checks I had queued up but I'm happy to wait for this series to
be applied.
Again, thanks for moving this along!

Subject: [PATCH] generic/602: Modify to work with agreed inheritance of DAX flag
Modifying the DAX flag on flies does not take effect immediately. The
easiest way to ensure the file state for this test is to use inheritance
of the parent directory DAX state.
Modify the test to use 2 directories which we can switch the DAX state on
and create the test files in those directories after setting the desired
state.
