I just think it is unnecessary especially because those warnings are not really worth to care for as they produce a bunch of false positives and that's why they're not enabled by default. IOW, I take them with a grain of salt. In this particular case, I would care about the code not doing any unnecessary work if it can be helped. And the warning can take a hike... :-) But I can apply the patch if you prefer. Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
