Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

No, it means "Hey, your data is bad. get some new data from the peer." -
if you tell both sides that they don't have good data, and that all
their blocks are outdated, which one should drbd use? ;-) They are both

It's possible that this case hasn't been tested well, simply because no
developer thought of trying it. (Which is usually a good indicator for a
real bug.)
