I don’t know if this is the correct place where to ask, but anyway.
Time ago I subscribed to the kernel component in order to receive emails.
Now I would like to unsubscribe, but I don’t remember how I configured that.
I looked in Preferences → Email Preferences. There is nothing in the Watching list.
Obviously I’m not in the kernel-maintainer group. Simply my email is automatically added to the CC list for the kernel bugs.
Go to Overview - rpms/kernel - src.fedoraproject.org and make sure you are
logged in, then click on the ‘watch’ button/dropdown and set it to
‘Unwatch’ or whatever subset of things you want to watch.
