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. -- Cheers, Stephen Rothwell
