xfs: test rmapbt updates are correct with insert/collapse range
Make sure that we update the rmapbt correctly when we collapse-range a file and the extents on both sides of the hole can be merged. We can construct this pretty trivially with insert-range and write, so test that too. Signed-off-by: Darrick J.
