Perhaps a compile-time test to check if the argument is a constant, and only in that case call your new kmalloc, otherwise a non-inline kmalloc call? With your current patch, a non-constant size argument to kmalloc means that the function is inlined anyway, leading to unnecessary bloat in the resulting image.
