Documentation: process: replace outdated LTS table w/ link

2022-10-24T17:27:01Z

The existing table was a bit outdated. 3.16 was EOL in 2020. 4.4 was EOL in 2022. 5.10 is new in 2020. 5.15 is new in 2021. We'll see if 6.1 becomes LTS in 2022. Rather than keep this table updated, it does duplicate information from multiple kernel.org pages. Make one less duplication site that needs to be updated and simply refer to the kernel.org page on releases.

docs: netdev: offer performance feedback to contributors

2022-10-24T10:03:44Z

Some of us gotten used to producing large quantities of peer feedback at work, every 3 or 6 months. Extending the same courtesy to community members seems like a logical step. It may be hard for some folks to get validation of how important their work is internally, especially at smaller companies which don't employ many kernel experts. The concept of "peer feedback" may be a hyperscaler / silicon valley thing so YMMV. Hopefully we can build more context as we go. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

Pull Kbuild updates from Masahiro Yamada: - Remove potentially incomplete targets when Kbuid is interrupted by SIGINT etc in case GNU Make may miss to do that when stderr is piped to another program. - Rewrite the single target build so it works more correctly. - Fix rpm-pkg builds with V=1. - List top-level subdirectories in ./Kbuild. - Ignore auto-generated __kstrtab_* and __kstrtabns_* symbols in kallsyms. - Avoid two different modules in lib/zstd/ having shared code, which potentially causes building the common code as build-in and modular back-and-forth. - Unify two modpost invocations to optimize the build process. - Remove head-y syntax in favor of linker scripts for placing particular sections in the head of vmlinux. - Bump the minimal GNU Make version to 3.82. - Clean up misc Makefiles and scripts. * tag 'kbuild-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (41 commits) docs: bump minimal GNU Make version to 3.82 ia64: simplify esi object addition in Makefile Revert "kbuild: Check if linker supports the -X option" kbuild: rebuild .vmlinux.export.o when its prerequisite is updated kbuild: move modules.builtin(.modinfo) rules to Makefile.vmlinux_o zstd: Fixing mixed module-builtin objects kallsyms: ignore __kstrtab_* and __kstrtabns_* symbols kallsyms: take the input file instead of reading stdin kallsyms: drop duplicated ignore patterns from kallsyms.c kbuild: reuse mksysmap output for kallsyms mksysmap: update comment about __crc_* kbuild: remove head-y syntax kbuild: use obj-y instead extra-y for objects placed at the head kbuild: hide error checker logs for V=1 builds kbuild: re-run modpost when it is updated kbuild: unify two modpost invocations kbuild: move vmlinux.o rule to the top Makefile kbuild: move .vmlinux.objs rule to Makefile.modpost kbuild: list sub-directories in ./Kbuild Makefile.compiler: replace cc-ifversion with compiler-specific macros ...

docs: bump minimal GNU Make version to 3.82

2022-10-06T00:16:21Z

GNU Make 3.81 fails in CONFIG_RUST=y builds. rust/Makefile:105: *** multiple target patterns. Stop. make[1]: *** [prepare] Error 2 make: *** [__sub-make] Error 2 The error message is unclear, but the reason is because the 'private' keyword is only supported since GNU Make 3.82. GNU Make 3.81 is still able to build the kernel when CONFIG_RUST is disabled, but it might be a good timing to raise the minimal GNU Make version. Perhaps, I am the last person who was testing GNU Make 3.81. GNU Make 3.81 was released in 2006, GNU Make 3.82 in 2010. Signed-off-by: Masahiro Yamada Reviewed-by: Miguel Ojeda
