@Andrea: when you fix a reported issue, next time please include a
"Link: <url>" that links to the report, as explained in the
documentation (see submitting-patches.rst). Linus wants these tags(¹)
and my regression tracking efforts rely on them (that'S why I had to
write this mail to tell regression tracking bot with above command that
the issue has been fixed). tia!

Ciao, Thorsten
