I am trying to get it retested by syzbot for the original issue, to be
sure the original report is still fixed.

I sent:
Reported-by: syzbot+740e04c2a93467a0f8c8@xxxxxxxxxxxxxxxxxxxxxxxxx
Closes: https://syzkaller.appspot.com/bug?extid=740e04c2a93467a0f8c8
#syz unfix

And then followed by Reported+Closes+:
#syz test

but syzbot does not want to retest it:
"This bug is already marked as fixed. No point in testing."

Anyone knows how to re-test this against old report?

Best regards,
Krzysztof
