Yea, there was a 0-day bug that caused it to ignore Wunused-function warnings. Apparently 0-day also forces CONFIG_WERROR=n, so the build erroneously succeeded.
The Wunused-function bug is fixed now on 0-day, and the fixed shadow stack branch re-tested by it. Dave had pushed the shadow stack fix to his repo as well, so I'm assuming he will handle getting the fix into tip. But please let me know if you need anything from me, and sorry for the hassle.
