If you want to find issues affecting the next release, then that's the
right choice.  But if you want to find issues that still need fixes
uploaded, then "unstable" is the right choice.  Any fixes in testing
need to go via unstable.

I'm just one person on the kernel team, and not the most active at the
moment.  Salvatore Bonaccorso is doing most of the security updates.

If syzbot is able to distinguish bugs that are reproducible on Debian
patched kernels but not in the corresponding stable releases, I think
that would be very useful to us.  My guess is that this would be a
manageable rate of bugs and we could receive those privately.  What do
you think, Salvatore?

If this isn't possible, then it's unlikely we will have the time to
look at the issues.  You can create a public web dashboard but I don't
know if that's going to help anyone.
