The patchesmade test 240 in the xfstests suite pass when
it consistently did not for me without it.
However I found that test 104 hung the two times I tried it.
At first I thought it could have been just taking a long time
but the fsstress processes were unkillable and shutdown
didn't complete either. I tried again after removing the
patches and 104 passed again.
