1. You did not follow entirely my advice here. Read again what I asked
you to fix in commit msg.

2. No improvements in subject - ignored comment.

Wrong path - it should be full path with /schemas/ just like it was last
time. However such file does not exist, so again as I said - you did not
test this patch. It's non-bisectable patchset. Order it properly. don't
ignore the comments.

This is a friendly reminder during the review process.

It seems my previous comments were not fully addressed. Maybe my
feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all
requested changes or keep discussing them.

Thank you.

Stray new line. Drop it.
