Hi all,

After merging the ftrace tree, today's linux-next build (x86_64
allmodconfig) failed like this:

kernel/trace/trace_functions_graph.c: In function '__trace_graph_retaddr_entry':
kernel/trace/trace_functions_graph.c:151:14: error: implicit declaration of function 'call_filter_check_discard' [-Wimplicit-function-declaration]
151 | if (!call_filter_check_discard(call, entry, buffer, event))
| ^~~~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

21e92806d39c ("function_graph: Support recording and printing the function return address")

interacting with commit

49e4154f4b16 ("tracing: Remove TRACE_EVENT_FL_FILTERED logic")

I have used the ftrace tree from next-20241009 for today.
