But this is wrong. If I use the old doc2000 driver, with ecc_strength =
2, and it works fine for me, and I am happy that UBI scrubs for a single
bit-flip, why should my system become broken because someone decided
that now UBI should start scrubbing on 2 bit-flips?
We should not change the defaults - if I do not set the threshold via
sysfs of in the driver, it should be 1.
Unless I am completely confused, we should change this, CC -stable if
needed, and ask dwmw2 to merge that.
