Markus, I think my commit comments is a sufficiently clear description
for this patch. Someone has told me not to send commit comments again
and again when it is enough clear. Because it only wastes the precious
time of the maintainer and very very little help for patch improvement.

BTW, In the past week, you asked me to change the commit comments in my
6 patches like this one. Let me return to the essence of patch, point out
that the code problems and better solutions will be more popular.
