From: Masahiro Yamada Date: Tue, 7 Jul 2020 09:21:17 +0000 (+0900) Subject: kbuild: trace functions in subdirectories of lib/ X-Git-Tag: v5.15~3138^2~6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b16838c608ef97c29896518117c30a2aa3931fac;p=platform%2Fkernel%2Flinux-starfive.git kbuild: trace functions in subdirectories of lib/ ccflags-remove-$(CONFIG_FUNCTION_TRACER) += $(CC_FLAGS_FTRACE) exists here in sub-directories of lib/ to keep the behavior of commit 2464a609ded0 ("ftrace: do not trace library functions"). Since that commit, not only the objects in lib/ but also the ones in the sub-directories are excluded from ftrace (although the commit description did not explicitly mention this). However, most of library functions in sub-directories are not so hot. Re-add them to ftrace. Going forward, only the objects right under lib/ will be excluded.
