This series improved my case of a WARN_ON triggering in trace_graph_return, the last return_to_handler entry in the stack dump has the caller in parenthesis rather than return_to_handler. It gives the caller, it would be nice if it could output the actual function being traced, and then continue the caller. But at least this is a significant improvement. Thanks for the quick turnaround. Tested-by: Nicholas Piggin <npig...@gmail.com>
