Martin Kaiser 91a5409002 maple_tree: fix tracepoint string pointers ... maple_tree tracepoints contain pointers to function names. Such a pointer is saved when a tracepoint logs an event. There's no guarantee that it's still valid when the event is parsed later and the pointer is dereferenced. The kernel warns about these unsafe pointers. event 'ma_read' has unsafe pointer field 'fn' WARNING: kernel/trace/trace.c:3779 at ignore_event+0x1da/0x1e4 Mark the function names as tracepoint_string() to fix the events. One case that doesn't work without my patch would be trace-cmd record to save the binary ringbuffer and trace-cmd report to parse it in userspace. The address of __func__ can't be dereferenced from userspace but tracepoint_string will add an entry to /sys/kernel/tracing/printk_formats Link: https://lkml.kernel.org/r/20251030155537.87972-1-martin@kaiser.cx Fixes: 54a611b605 ("Maple Tree: add new data structure") Signed-off-by: Martin Kaiser <martin@kaiser.cx> Acked-by: Liam R.
