We discourage sending trivial patches to clean up checkpatch warnings.
There are other tools which lead to patches of similarly low value
like some coccicheck warnings. The warnings are useful for new code
but fixing them in the existing code base is a waste of review time.
Broaden the example given in the doc a little bit.

The text was presenting the team, the the e-mail address, then some of
the expectations, then what form of e-mail is expected. By switching
the e-mail paragraph two paragraphs later and dropping the "Contact"
sub-section, we can have a more natural flow that presents the team,
then its expectation, then how to best contribute, then where to send.
And more importantly, it increases the chances that reporters have read
the prerequisites before finding the e-mail address.

Some bug reports sent to the security team sometimes lack any explanation,
are only AI-generated without verification, or sometimes it can simply be
difficult to have a conversation with an invisible reporter belonging to
an opaque team. This fortunately remains rare but the trend has been
steadily increasing over the last years and it seems important to clarify
what developers expect from reporters to avoid frustration on any side and
keep the process efficient.

Python is listed as an optional dependency, but this is not
true, as:
1) arm (multi_v7_defconfig and other defconfigs) and arm64 defconfig
needs it due to DRM_MSM dependencies;
2) CONFIG_LTO_CLANG runs a python script at scripts/Makefile.vmlinux_o;
3) kernel-doc is called during compilation when some DRM options
like CONFIG_DRM_I915_WERROR are enabled;
4) allyesconfig/allmodconfig will enable CONFIG_* dependencies
that needs it;
5) besides DRM, other subsystems seem to have logic calling *.py
scripts.
So, better document that and change the dependency from optional
to mandatory to reflect the current needs.

Pull documentation updates from Jonathan Corbet:
"It has been a relatively busy cycle for docs, especially the build
system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the
turn of the millennium. Over the following 25 years, it accumulated
a vast amount of cruft, all in a language few people want to deal
with anymore. Mauro's Python replacement in 6.16 faithfully
reproduced all of the cruft in the hope of avoiding regressions.
Now that we have a more reasonable code base, though, we can work
on cleaning it up; many of the changes this time around are toward
that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository
links.
...and lots of fixes and updates"

It appears that folks "less versed in kernel coding" think that its
good style to document every function, even if they have no useful
information to pass to the future readers of the code. This used
to be just a waste of space, but with increased kdoc format linting
it's also a burden when refactoring the code.

Pull compiler version requirement update from Arnd Bergmann:
"Require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other
architectures to the same version. gcc-8 is used is Debian 10 and Red
Hat Enterprise Linux 8, both of which are still supported, and
binutils 2.30 is the oldest corresponding version on those.
Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as
the system compiler but additionally include toolchains that remain
supported.
With the new minimum toolchain versions, a number of workarounds for
older versions can be dropped, in particular on x86_64 and arm64.
Importantly, the updated compiler version allows removing two of the
five remaining gcc plugins, as support for sancov and structeak
features is already included in modern compiler versions.
I tried collecting the known changes that are possible based on the
new toolchain version, but expect that more cleanups will be possible.
Since this touches multiple architectures, I merged the patches
through the asm-generic tree."

"Here are the driver core / kernfs changes for 6.16-rc1.
Not a huge number of changes this development cycle, here's the

- kernfs locking tweaks, pushing some global locks down into a per-fs
image lock
- rust driver core and pci device bindings added for new features.
- sysfs const work for bin_attributes.
The final churn of switching away from and removing the
transitional struct members, "read_new", "write_new" and
"bin_attrs_new" will come after the merge window to avoid
unnecesary merge conflicts.
- auxbus device creation helpers added
- fauxbus fix for creating sysfs files after the probe completed
properly
- other tiny updates for driver core things.

Update the documentation to reflect the migration of the following
architectures to the centralized syscall table format:
arc, arm64, csky, hexagon, loongarch, nios2, openrisc, riscv
As of commit 3db80c999debbad ("riscv: convert to generic syscall table"),
these architectures no longer rely on include/uapi/asm-generic/unistd.h.
Instead, syscall table headers (syscall_table_{32,64}.h) are generated by
scripts/syscalltbl.sh based on entries in scripts/syscall.tbl, with ABIs
specified in arch/*/kernel/Makefile.syscalls.
For the convenience of developers working with older kernel versions, the
original documentation is fully retained, with new sections added to
cover the scripts/syscall.tbl approach.
Verified with `make htmldocs`.

Commit a3e8fe814ad1 ("x86/build: Raise the minimum GCC version to 8.1")
raised the minimum compiler version as enforced by Kbuild to gcc-8.1
and clang-15 for x86.
This is actually the same gcc version that has been discussed as the
minimum for all architectures several times in the past, with little
objection. A previous concern was the kernel for SLE15-SP7 needing to
be built with gcc-7. As this ended up still using linux-6.4 and there
is no plan for an SP8, this is no longer a problem.
Change it for all architectures and adjust the documentation accordingly.
A few version checks can be removed in the process. The binutils
version 2.30 is the lowest version used in combination with gcc-8 on
common distros, so use that as the corresponding minimum.

Update the debugfs documentation to indicate that debugfs_remove()
should be used to clean up debugfs entries.
In commit a3d1e7eb5abe ("simple_recursive_removal(): kernel-side rm -rf
for ramfs-style filesystems"), function debugfs_remove_recursive()
was made into an alias for debugfs_remove():
#define debugfs_remove_recursive debugfs_remove
Therefore, drivers should just use debugfs_remove() going forward.

"Core & protocols:
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls)
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked) in
BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream
performance up to 2x.
- Improve performance of contended connect() by 200% by searching for
an available 4-tuple under RCU rather than a spin lock. Bring an
additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles. There are up to 4
namespace roles but we used to have just 2 netns pointer arguments,
interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout in
TCP.
- Support masking port and DSCP in routing rule matches.

Pull documentation updates from Jonathan Corbet:
"It has been a reasonably busy cycle for docs...
- Significant changes throughout the tree to bring Python code up to
current standards and raise the minimum Python required to 3.9
Much of this is preparatory to replacing the ancient Perl
scripts/kernel-doc horror with a slightly less horrifying Python
implementation, expected for 6.16
- Update the minimum Sphinx required to 3.4.3, allowing us to remove
a bunch of older compatibility code
- Rework and improve the generation of the ABI documentation
(All of the above done by Mauro)
- Lots of translation updates. Alex Shi and Yanteng Si are taking on
responsibility for the Chinese translations going forward; that
work will still get to you via docs-next
- Try to standardize the format for indicating a developer's
affiliation in commit tags
- Clarify the TAB's role in CoC enforcement actions
- Try to spell out the rules for when a commit tag can name another
developer without their explicit permission
Plus lots of other typo fixes and updates"

Point out that explicit permission is usually needed to tag other people
in changes, but mention that implicit permission can be sufficient in
certain cases. This fixes slight inconsistencies between Reported-by:
and Suggested-by: and makes the usage more intuitive.
While at it, explicitly mention the dangers of our bugzilla instance, as
it makes it easy to forget that email addresses visible there are only
shown to logged-in users.
The latter is not a theoretical issue, as one maintainer mentioned that
his employer received a EU GDPR (general data protection regulation)
complaint after exposing a email address used in bugzilla through a tag
in a patch description.

cross-ref of README
Commit fb12098d8ee4 ("docs: submit-checklist: Allow creating
cross-references for ABI README") assumes that the path of
"Documentation/ABI/README" would be converted to a cross-ref to
the README.
However, as the README is included by the "kernel-abi" directive
at Documentation/admin-guide/abi.rst, the expected conversion
does not happen.
Instead, use the path where the "kernel-abi" directive exists for
the conversion to work. Restore the original path of README in
inline-literal form as an additional note for readers of the .rst
file.
Apply the same changes for translations.

Updates the document to clearly describe the scope and role the TAB plays
in making decisions on unresolved violations. If and when the CoC has to
make a call on instituting a ban, it doesn't act without the TAB's approval
and only when the TAB approves it with 2/3 vote in favor of the measure.
These changes ensure that the TAB role and its oversight on CoC measures
is consistently described throughout the document.

We haven't had much discussion on the list about this, but
a handful of people have been confused about rules on
posting selftests for fixes, lately. I tend to post fixes
with their respective selftests in the same series.
There are tradeoffs around size of the net tree and conflicts
but so far it hasn't been a major issue.

Add a reference to my new book, The Linux Memory Manager, an in-depth
exploration of the memory management subsystem, to
process/kernel-docs.rst.
This is not yet published, but the full draft is available on pre-order, so
it seems worthwhile adding it here. The situation is made clear in the
'notes' section.
The 'pre-release' was made available in February 2025, and full release is
scheduled for Fall 2025. The book's ISBN-13 is 978-1718504462.
The document will be updated upon release to reflect this.
