modpost: Declare extra_warn with unused attribute

2026-03-30T05:45:34+00:00

A recent strengthening of -Wunused-but-set-variable (enabled with -Wall)
in clang under a new subwarning, -Wunused-but-set-global, points out an
unused static global variable in scripts/mod/modpost.c:

  scripts/mod/modpost.c:59:13: error: variable 'extra_warn' set but not used [-Werror,-Wunused-but-set-global]
     59 | static bool extra_warn;
        |             ^

This variable has been unused since commit 6c6c1fc09de3 ("modpost:
require a MODULE_DESCRIPTION()") but that is expected, as there are
currently no extra warnings at W=1 right now. Declare the variable with
the unused attribute to make it clear to the compiler that this variable
may be unused.

kbuild: modules-cpio-pkg: Respect INSTALL_MOD_PATH

2026-03-30T05:38:26+00:00

The modules-cpio-pkg target added in commit 2a9c8c0b59d3 ("kbuild: add
target to build a cpio containing modules") is incompatible with
initramfs with merged /lib and /usr/lib directories [1]. "/lib" cannot
be a link and directory at the same time.
Respect a non-empty INSTALL_MOD_PATH in the modules-cpio-pkg target so
that `make INSTALL_MOD_PATH=/usr modules-cpio-pkg` results in the same
module install location as `make INSTALL_MOD_PATH=/usr modules_install`.

Tested with Fedora distribution initramfs produced by dracut.

livepatch/klp-build: Fix inconsistent kernel version

2026-03-16T19:50:17+00:00

If .config hasn't been synced with auto.conf, any recent changes to
CONFIG_LOCALVERSION* may not get reflected in the kernel version name.

Use "make syncconfig" to force them to sync, and "make -s kernelrelease"
to get the version instead of having to construct it manually.

scripts: kconfig: merge_config.sh: pass output file as awk variable

2026-03-11T07:37:50+00:00

The refactoring commit 5fa9b82cbcfc5 ("scripts: kconfig:
merge_config.sh: refactor from shell/sed/grep to awk") passes
$TMP_FILE.new as ARGV[3] to awk, using it as both an output destination
and an input file argument. When the base file is empty, nothing is
written to ARGV[3] during processing, so awk fails trying to open it
for reading:

    awk: cmd. line:52: fatal: cannot open file
    `./.tmp.config.grcQin34jb.new' for reading: No such file or directory
    mv: cannot stat './.tmp.config.grcQin34jb.new': No such file or directory

Pass the output path via -v outfile instead and drop the FILENAME ==
ARGV[3] { nextfile }.
