I guess it will point to

It sure did!:
commit 7b4375c36a4c0e1b4b97ccbcdd427db5a460e04f Author: Francis Laniel flaniel@linux.microsoft.com Date: Fri Oct 20 13:42:49 2023 +0300
tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols
commit b022f0c7e404887a7c5229788fc99eff9f9a80d5 upstream.
Reverting that commit made the build pass again.
