Thanks, but when fixing a bug, please always describe the runtime
effects of that bug.  Amongst other things, other people need this

Which is a reason why we're now adding the "Closes:" tag after
Reported-by:.

I googled the sysbot email address and so added

to the changelog.

I'll assume that a -stable kernel backport is needed.
