Currently kernel-doc does not identify some cases of probable kernel
doc comments, for e.g. pointer used as declaration type for identifier,
space separated identifier, etc.

Some example of these cases in files can be:
i)" *  journal_t * jbd2_journal_init_dev() - creates and initialises a journal structure"
in fs/jbd2/journal.c

ii) "*      dget, dget_dlock -      get a reference to a dentry" in
include/linux/dcache.h

iii) "  * DEFINE_SEQLOCK(sl) - Define a statically allocated seqlock_t"
in include/linux/seqlock.h

Also improve identification for non-kerneldoc comments. For e.g.,

i) " *	The following functions allow us to read data using a swap map"
in kernel/power/swap.c does follow the kernel-doc like syntax, but the
content inside does not adheres to the expected format.

Improve parsing by adding support for these probable attempts to write
kernel-doc comment.

The kernel now has a number of testing and debugging tools, and we've
seen a bit of confusion about what the differences between them are.

Add a basic documentation outlining the testing tools, when to use each,
and how they interact.

This is a pretty quick overview rather than the idealised "kernel
testing guide" that'd probably be optimal, but given the number of times
questions like "When do you use KUnit and when do you use Kselftest?"
are being asked, it seemed worth at least having something. Hopefully
this can form the basis for more detailed documentation later.

Add the newly created regression mailing list finally created after it
already had been agreed on during the maintainers summit 2017 (see
https://lwn.net/Articles/738216/ ). The topic was recently discussed
again, where an idea to create a broader list for all issues was
discussed, but Linus preferred a more targeted list:
https://lkml.kernel.org/r/CAHk-=wgiYqqLzsb9-UpfH+=ktk7ra-2fOsdc_ZJ7WF47wS73CA@mail.gmail.com/

Hence, the creation for that list was asked for and granted:
https://bugzilla.kernel.org/show_bug.cgi?id=212557

In the end it became regressions@lists.linux.dev instead of
linux-regressions@lists.linux.dev as 'Linux' would have been redundant
in the latter case.
