Why do all the patches have the same subject line?

I guess it's correct for the first one, but can you explain what's up
with #2 and #3?

If the second one isn't upstream, please explain in detail why not and
how 4.9 differs from upstream so that it requires a custom backport.

The third one just looks like a different patch altogether with a wrong
subject line?
