This causes xfs/068 to fail because it changes the file creation
pattern that results from a specific fsstress random seed. As such,
I added this to xfs/068:

FSSTRESS_AVOID="-f insert=0 $FSSTRESS_AVOID"

To turn off the insert operation for that test and hence produce the
expected tree of files.

Cheers,

Dave.
