Mauro Carvalho Chehab 0b54c2e34b scripts/kernel-doc: ignore identifier on anonymous enums
When anonymous enums are used, the identifier is empty.

While, IMO, it should be avoided the usage of such enums,
adding support for it is not hard.

So, postpone the check for empty identifiers to happen
only at the dump phase.

Aditya Srivastava 084aa00162 scripts: kernel-doc: fix attribute capture in function parsing
Currently, kernel-doc warns for function prototype parsing on the
presence of attributes "__attribute_const__" and "__flatten" in the
definition.

There are 166 occurrences in ~70 files in the kernel tree for
"__attribute_const__" and 5 occurrences in 4 files for "__flatten".

Out of 166, there are 3 occurrences in three different files with
"__attribute_const__" and a preceding kernel-doc; and, 1 occurrence in
./mm/percpu.c for "__flatten" with a preceding kernel-doc. All other
occurrences have no preceding kernel-doc.

Add support for  "__attribute_const__" and "__flatten" attributes.

A quick evaluation by running 'kernel-doc -none' on kernel-tree reveals
that no additional warning or error has been added or removed by the fix.

Marvell has an annoying habit of moving stuff around their web site
every full moon, and often just removing documents altogether.

At this point basically none but four of the links still works and even
those that work today weren't working for a long period of time
previously. That is a shame because (short of the product briefs) the
documents tend to be quite useful.

Let's replace them with known working versions of IA's Wayback Machine
links. That seems to be about the only way of getting a URL that's going

Borislav Petkov 875f82cb37 Documentation/submitting-patches: Extend commit message layout description
Add more blurb about the level of detail that should be contained in a
patch's commit message. Extend and make more explicit what text should
be added under the --- line. Extend examples and split into more easily
palatable paragraphs.

This has been partially carved out from a tip subsystem handbook
patchset by Thomas Gleixner:

  https://lkml.kernel.org/r/20181107171010.421878737@linutronix.de

and incorporates follow-on comments.

Thorsten Leemhuis 315c4e45f1 docs: reporting-issues.rst: explain how to decode stack traces
Replace placeholder text about decoding stack traces with a section that
properly describes what a typical user should do these days. To make
it works for them, add a paragraph in an earlier section to ensure
people build their kernels with everything that's needed to decode stack
traces later.

Lukas Bulwahn 692180345d MAINTAINERS: clarify responsibility for checkpatch documentation
As discussed, Dwaipayan and Lukas take the responsibility for maintaining
the checkpatch documentation that is currently being built up.

To be sure that the checkpatch maintainers and the corresponding
documentation maintainers can keep the content synchronized, add them as
reviewers to the counterpart.

Dwaipayan Ray 52178ce013 checkpatch: add verbose mode
Add a new verbose mode to checkpatch.pl to emit additional verbose
test descriptions. The verbose mode is optional and can be enabled
by the flag -v or --verbose.

The test descriptions are parsed from the checkpatch documentation
file at `Documentation/dev-tools/checkpatch.rst`. The test
descriptions in the docs are kept in a fixed format grouped by
usage. Some examples of this format are:

  **LINE_SPACING**
    Vertical space is wasted given the limited number of lines an
    editor window can display when multiple blank lines are used.

  **MISSING_SIGN_OFF**
    The patch is missing a Signed-off-by line.  A signed-off-by
    line should be added according to Developer's certificate of
    Origin.

To avoid lengthy output, the verbose description is printed only
for the first instance of a particular message type.

The --verbose option cannot be used along with the --terse option.

Verbose mode can be used with the --list-types option.
The --list-types output also supports color coding now.

Add documentation for kernel script checkpatch.pl.
This documentation is also parsed by checkpatch to
enable a verbose mode.

The checkpatch message types are grouped by usage. Under
each group the types are described briefly. 34 of such
types are documented.

Aditya Srivastava a746fe32cd scripts: kernel-doc: fix typedef support for struct/union parsing
Currently, there are ~1290 occurrences in 447 files in the kernel tree
'typedef struct/union' syntax for defining some struct/union. However,
kernel-doc currently does not support that syntax. Of the ~1290
occurrences, there are four occurrences in ./include/linux/zstd.h with
typedef struct/union syntax and a preceding kernel-doc; all other
occurrences have no preceding kernel-doc.

Add support for parsing struct/union following this syntax.

Yang Shi 1eff491fc4 doc: memcontrol: add description for oom_kill
When debugging an oom issue, I found the oom_kill counter of memcg is
confusing.  At the first glance without checking document, I thought it
just counts for memcg oom, but it turns out it counts both global and
memcg oom.

The cgroup v2 documents it, but the description is missed for cgroup v1.
