From: Ian Rogers Date: Tue, 19 Nov 2024 01:16:30 +0000 (-0800) Subject: perf stat: Move stat_config into config.c X-Git-Tag: v6.14-rc1~120^2~105 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9557d1562a8f49e8803265b4b30045f690b6d041;p=thirdparty%2Flinux.git perf stat: Move stat_config into config.c stat_config is accessed by config.c via helper functions, but declared in builtin-stat. Move to util/config.c so that stub functions aren't needed in python.c which doesn't link against the builtin files. To avoid name conflicts change builtin-script to use the same stat_config as builtin-stat. Rename local variables in tests to avoid shadow declaration warnings.
