It sure did!:

  commit 7b4375c36a4c0e1b4b97ccbcdd427db5a460e04f
  Author: Francis Laniel <flaniel@...ux.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.
