Nono, I try to remove the swap space occupied by pages that

Ok then do it for all pages that go back not just for those leftover from the moving of pages to the inactive list (why would you move those???)

I do. The only pages that are exempt are the pages that move
from the active list to the inactive list, because those will
probably be evicted soon enough.

Maybe the hunk does apply in a different location than I thought.

I suspect that's the case ...

If you do that in the loop over the pages on active list then it would make sense. But in that case you need another piece of it doing the same to the pages that are released at the end of shrink_active_list().

... because I think this is what my patch does :)
