In my case the particular code I was digging into was within the function `squash_the_stupid_serial_number(...)` as seen here: https://cregit.linuxsources.org/code/6.13/arch/x86/kernel/cpu/common.c.html#328 https://cregit.linuxsources.org/code/6.13/arch/x86/kernel/cp... Unfortunately the direct line-number link above doesn't seem to provide the same view as manually choosing "squash_the_stupid_serial_number(...)" rather than "Overall" in the selection/option menu accessible via the page link: https://cregit.linuxsources.org/code/6.13/arch/x86/kernel/cpu/common.c.html https://cregit.linuxsources.org/code/6.13/arch/x86/kernel/cp... (Apparently the only code directly from Linus' original commit for that function is `, lo, hi`. :) And, unfortunately, being from the pre-git era, it is lacking any sort of informative commit message...) Also, as the documentation mentions the token-tracing isn't perfect, e.g. the `squash_the_stupid_serial_number` name did actually exist before the cregited commit: https://github.com/torvalds/linux/commit/0a488a53d7ca46ac638c30079072c57e50cfcc7b https://github.com/torvalds/linux/commit/0a488a53d7ca46ac638... (Perhaps this could be related to there being multiple function implementations selected via #ifdef?)
