This is particularly confusingfor requested values that get forced down by unmet dependencies orclamped by ranges.Add an opt-in diagnostic controlled by KCONFIG_WARN_CHANGED_INPUT. Emitthe warnings from conf_write() and conf_write_defconfig() after valueresolution. Print the diagnostic to stderr directly, not through thenormal message callback, so it remains visible when conf is run with -s,such as from make -s.Keep the diagnostic out of the conf_message() formatting buffer so longwarning lists are not truncated, and mark processed symbols as writtenbefore the SYMBOL_WRITE check so duplicate menu nodes cannot emitduplicate warnings.Document the new environment variable and add tests for olddefconfig,savedefconfig, and the silent-conf path.Signed-off-by: Pengpeng Hou <pengpeng@iscas.ac.cn>Tested-by: Julian Braha <julianbraha@gmail.com>Link: https://patch.msgid.link/20260611060000.23858-1-pengpeng@iscas.ac.cnSigned-off-by: Nathan Chancellor <nathan@kernel.org> List of files: /linux/scripts/kconfig/tests/warn_changed_input/__init__.py Thu, 11 Jun 2026 08:00:00 +0200 Pengpeng Hou <pengpeng@iscas.ac.cn>
