OK, I'll try not to take so long to have a look at it this time.

This isn't something I feel really strongly about, but we could consider admin-guide/reporting-regressions.txt (or just regressions.txt) process/regression-policy.txt > MAINTAINERS | 2 + > 5 files changed, 1112 insertions(+) > create mode 100644 Documentation/admin-guide/regressions-users.rst > create mode 100644 Documentation/process/regressions-devs.rst > [...] > +Send a mail to the regressions mailing list (regressions@xxxxxxxxxxxxxxx) while > +CCing the Linux kernel's regression tracker (regressions@xxxxxxxxxxxxx); if the > +issue might better be dealt with in private, feel free to omit the list. Perhaps a separate concern, but might you want to set up an @kernel.org alias for the regression tracker? Trust me, you're not gonna want to run it forever, and the ability to quickly redirect the mail may prove to be a nice thing to have. An email address with your domain sitting in the docs will circulate for years after it gets changed. > + > +Additional details about regressions > +------------------------------------ > + > + > +What is the goal of the "no regressions rule"? > +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > + > +Users should feel safe when updating kernel versions and not have to worry > +something might break.

I'm not really convinced that we need all those Quotations From Chairman Linus, but I won't fight about it either :) In general, though, unless objections show up, I don't see any real reason to not apply this one.
