HAVE_FTRACE_GRAPH_FUNC does not exist on 6.13, so FPROBE is effectively disabled by this backport.

Is this missing (and only this?): commit a762e9267dca843ced943ec24f20e110ba7c8431 Author: Masami Hiramatsu (Google) mhiramat@kernel.org Date: Thu Dec 26 14:13:34 2024 +0900

ftrace: Add CONFIG_HAVE_FTRACE_GRAPH_FUNC
