Well, that's a good hint, but it's really just a symptom. You effectively
just made the test-program not even try to flush the data to disk, so the
page cache would stay in memory, and you'd not see the corruption as well.

So you basically disabled the code that tried to trigger the bug more

But the reason I say it's interesting is that "WB_SYNC_NONE" is very much
implicated in mm/page-writeback.c, and if there is a bug triggered by
WB_SYNC_NONE writebacks, then that would explain why page-writeback.c also
