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
