Running the tests with the dev2 branch, which includes all of the
ext4-specific ZERO_RANGE patches, we see a regression with shared/243
with 4k and 1k block sizes (as well as 4k in no-journal mode):
shared/243 3s ... [15:09:34] [15:09:35] [failed, exit status 1] - output mismatch (see /results/results-4k/shared/243.out.bad)
