[DRBD-user] UpToDate and out-of-sync inconsistence

Hi all,

I am continuing to investigate this.
As a result, I found one fact.

This problem only occurs when the state transitions from "OutDated" to
"UpToDate".
And it never occurs when the state transitions from "Inconsistent" to
"UpTodate".

Probably,I presume that the state transition from "OutDated" to "UpToDate"
is not exclusive in the state transition and asynchronous calculation.

Is this a specification? Or is it a bug?
If it's a bug, where in the source code should I add exclusive processing?

I'm worried because I don't know how to fix it.
I would be grateful if anyone could tell me.

Best regards,
shuhei
