Hi Mario,

Not sure how you created this patchset, but you miss a Subject, and the
diff-stat.

Please use

git format-patch -o <output-dir> -3 --cover-letter

to generate patches, then fill the cover letter in.

Once your cover letter is ready, you can send the patches with

git send-email --to ... --cc ... <output-dir>/*.patch

Regards,

Boris
