PS1: 
All good in the code, but you will need to rebase this patch on the top of main branch.

It says "merge conflict", but I think there is no actual conflict. It's just that the adjacent lines, just before in the same file, were submitted in the other patch earlier.
Tell me if rebasing won't work, I will have a look.
