[RFC PATCH v1 02/26] docs: reporting-bugs: Create a TLDR how to report issues

[Thorsten Leemhuis]

Get straight to the point in a few paragraphs instead of forcing users
to read quite a bit of text, like the old approach did.

All normally needed fits into the first two paragraphs. The third is
dedicated to issues only happening in stable and longterm kernels, as
things otherwise get hard to follow. At the end explicitly spell out
that some issues need to be handled slightly different.

This TLDR naturally leaves lots of details out. But it will be good
enough in some situations, for example for users that recently reported
an issue or are familiar with reporting issues to FLOSS projects.

+The short guide (aka TL;DR)
+===========================
+
+This is how you report issues with the Linux kernel to its developers:
+
+If you deal with multiple issues at once, process each of them separately. Try
+your best guess which area of the kernel might be responsible for your issue.
+Check the `MAINTAINERS file
+<https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/MAINTAINERS>`_
+how developers of that particular area expect to be told about issues; note,
+it's rarely `bugzilla.kernel.org <https://bugzilla.kernel.org/>`_, as most
+subsystems expect reports by mail sent to their maintainers and their public
+mailing list!
+
+Check the archives of the determined destination thoroughly for existing
+reports; also search the LKML archives and the internet as a whole. If you can't
+find any, install the `latest Linux mainline version <https://kernel.org/>`_.
+Make sure to use a vanilla kernel and avert any add-on kernel modules externally
+developed; also ensure the kernel is running in a healthy environment and does
+not 'taint' itself before the issue occurs. If you can reproduce it, write a
+report to the destination you determined earlier. Afterwards keep the ball
+rolling by proactive testing, a status update now and then, and helping where
+you can.
+
+You can't reproduce an issue with mainline you want to see fixed in older
+version lines? Then make sure the line you care about still gets support.
+Install its latest release as vanilla kernel. If you can reproduce the issue
+there, try to find the commit that fixed it in mainline or any discussion
+preceding it: those will often mention if backporting is planed or impossible;
+if not, ask for it. In case you don't find anything, check if it's a regression
+specific to the version line that need to be bisected and report just like a
+problem in mainline with the stable mailing list CCed. If you reached this point
+without a solution, ask for advice by mailing the subsystem maintainer with the
+subsystem and stable mailing list in CC.
+
+If you deal with a regression, bisect it to find the culprit and CC or forward
+your report to its developers.
+
+Security issues are typically best report privately; also CC the security team
+or forward your report there.
