IMO, if I fail to online pages, I want to know I failed. I think that pr_err would be better than pr_debug and without CONFIG_DEBUG_VM. But at least, if not, envolve it with a CONFIG_DEBUG_VM, but change pr_debug to pr_info. > +#ifdef CONFIG_DEBUG_VM > pr_debug("memory offlining [mem %#010llx-%#010llx] failed\n", > (unsigned long long) start_pfn << PAGE_SHIFT, > ((unsigned long long) end_pfn << PAGE_SHIFT) - 1); > +#endif Same goes here.
