Nobody will going to remove simple_strtox() due to their convenience when it's related to parse something from the stream. Yes, overflow is possible, but here is a trade-off. Note, kstrtox() may not work at early boot stages when we need to parse stream (with mixed digits and text and symbols) without acquiring space from the heap, i.o.w. RO strings. -- With Best Regards, Andy Shevchenko
