Hi, Zhao Lei,

Thanks for taking a look! I was able to reproduce this and it looks like
a similar bug, this time coming from the parity scrubbing code instead
of the data scrubbing code. I didn't test scrubbing a degraded
filesystem, only replacing a missing device, so that's probably why I
didn't run into it. I'll take a closer look.

Thanks,
