I just had a quick look and tried Masami's git tree with the
topic/fprobe-on-fgraph branch and tried the ftrace selftests, which
resulted in the provided small fix.
But now that you ask, I can see that FPROBE is not available on s390
anymore with the full series, since HAVE_FTRACE_GRAPH_FUNC is not
available.
Also the s390 variant of arch_ftrace_fill_perf_regs() seems to be
incorrect.
Looks like some work is needed from our side.
