Hi, it could be a silly question, but better to ask... > + if (regs) > + start_backtrace(&frame, regs->regs[29], regs->pc); > + else > + start_backtrace(&frame, thread_saved_fp(task), > + thread_saved_pc(task)); Would this also work for task == current? Given that the original code had > - start_backtrace(&frame, > - (unsigned long)__builtin_frame_address(0), > - (unsigned long)__save_stack_trace); for the case, which seems correct (but I don't know much about arm64 arch in the kernel). Otherwise, I did not spot anything suspicious or wrong. Regards Miroslav
