Make people CC the recently created mailing list dedicated to Linux kernel regressions when reporting one. Some paragraphs had to be reshuffled and slightly rewritten during the process, as the text otherwise would have gotten unnecessarily hard to follow.
Signed-off-by: Thorsten Leemhuis <li...@leemhuis.info> --- v1->v2 * drop the bits that a would help a automatic tracking solution FWIW, a quick reminder about something I wrote in v1, but nobody said anything about it: now that we have a mailing list for regressions I was inclined to remove the "Make the report's subject start with '[REGRESSION]'" part from the text. But in the end I left it, to make it obvious on other lists that the mail is about a regression. Nevertheless, I'm still wondering if it should be toned down a bit, as it might be enough if the subject starts with "regression:" or contains the word somewhere.
