This statement is a gross oversimplification of the issues involved.

If you'll recall, this was already highlighted in the context of your
patch here:

http://www.spinics.net/lists/target-devel/msg11057.html

There are a number of comments on why the bug-fix was incorrect and
broken, the basics of what needed to be done and in what order it should
happen.

But instead of replying to the comments, this was your response:

http://www.spinics.net/lists/target-devel/msg11542.html

If you are authentically interested in understanding the issues
involved, you'll probably need to go back and comment on those topics
individually, instead of ignoring them.
