I agree. However, I think using resource_size_t is a bit better than unsigned long, so that we don't need to check the defination of it. - res->start = (unsigned long)kmalloc(*size, GFP_KERNEL); + res->start = (resource_size_t)kmalloc(*size, GFP_KERNEL); Is this change OK? -- To do great work, you have to have a pure mind. You can think only about the mathematics. Everything else is human weakness.
