Patch series "checkpatch.pl: warn about discouraged tags and missing Link:
tags", v4.
The first two changes make checkpatch.pl check for a few mistakes wrt to
links to bug reports Linus recently complained about a few times.
Avoiding those is also important for my regression tracking efforts a lot,
as the automated tracking performed by regzbot relies on the proper usage
of the Link: tag.
The third patch fixes a few small oddities noticed in existing code during
review of the two changes.
This patch (of 3):
Issue a warning when encountering URLs behind unknown tags, as Linus
recently stated ```please stop making up random tags that make no sense.
Just use "Link:"```[1]. That statement was triggered by an use of
'BugLink', but that's not the only tag people invented:
$ git log -100000 --no-merges --format=email -P \
--grep='^\w+:[ ]*http' | grep -Poh '^\w+:[ ]*http' | \
sort | uniq -c | sort -rn | head -n 20

Some of these non-standard tags make it harder for external tools that
rely on use of proper tags. One of those tools is the regression tracking
bot 'regzbot', which looks out for "Link:" tags pointing to reports of
tracked regressions.
The initial idea was to use a disallow list to raise an error when
encountering known unwanted tags like BugLink:; during review it was
requested to use a list of allowed tags instead[2].

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
