From: Darrick J. Wong <djwong@xxxxxxxxxx>
Fork these tests to check the same things with exchange-range as they do
for swapext, since the code porting swapext to commit-range has been
dropped.
I was going to fork xfs/789 as well, but it turns out that generic/714
covers this sufficiently so for that one, we just strike fiexchange from
the group tag.
