I have merged the 2 patches in Xen 4.16, 4.15 and 4.14. I noticed that 
the "released-acked-by" tags were removed.

We usually keep the commit message as-is (including tags). But I vaguely 
remember that we may have stripped the "released-acked-by" tag in the 
past. So I left it alone.

Also, it looks like the tools I am using to download the patches (b4) 
decided to move the "cherry-picked ..." line before the tags. I am not 
entirely sure why... So I have modified the commit message to re-add the 
line where you initially added (this is the correct place!).

Cheers,

Thank you very much!

Yeah, I cannot find any "Release-acked-by" from all the backported
patches so I removed that tag for convenience of the maintainer doing
the backport.

Thanks.

Hmmm this is strange...probably b4 thinks this "cherry picked commit" is
some kind of unnecessary information which shouldn't appear in the commit
message :)

My initial thought was adding the "cherry picked commit" would reduce
the maintainer's workload so the patch can be applied without any modification
but it seems that you still did some extra work....sorry about that.

Kind regards,
Henry

I am guessing 'b4' is removing all the tags and then append them at the end.

You did the right thing to add the cherry-pick tag. This is more my 
workflow that is broken :). I will have a look if I can fix it.

Indeed I'm trying to remember to strip those when doing backports, as they
aren't meaningful (but potentially confusing) on the stable branches.
