No. The subject is still wrong and my comments on compatible still 
remain. For the latter, I just replied on the original thread.

Wrong patch. And modified how? You need to list the changes from the 
last version one by one. This list should give the reviewer a clue as to 
which parts need to be reviewed again so we don't have to review the 
whole thing again nor remember what we said to change. The reviewer has 
probably reviewed 10s to 100 patches since the last version and doesn't 
remember what they said.
