You cannot leak kernel memory content. Either you clear the field or,
in the code which actually copies the data to userlevel, you copy again
field by field. The latter is far too slow. So you better clear all
fields.

Why? Tell this to people who are affected.

Name them. I've asked for it before and got the answer "it's mainly
ls". Now ls is debunked. So, provide more evidence that the
getdirentplus support is needed.

We're not talking about statlite. The ls case is about getdirentplus.
I fail to see evidence that it is really needed.
