Thanks for the patches, looks good.

But who is really the author of patches 1 and 2? You or Cezary? In the
first case, you can use the Co-Developed-By tag to give Cezary credit,
and otherwise you need to add a From line so that authorship is recorded
correctly.

Take a look at Documentation/process/submitting-patches.rst.

I know the entries here appear to be in mostly random order, but if
you're adding numerical ids towards the end, perhaps you can try to
insert them in order.
