Please do *always* post a patch. Maintainers receive lots of messages
like this one every single day, there's no point sending a message
saying "you might be interested in a patch I have" without sending
the patch, it wastes time and effort doing round trips. Just send it.
Same for the reproducers, if they're not too big, just send them to
the maintainers (not the mailing lists) so they have everything to
start working on when they open their mailbox.

Thanks,
Willy
