The fixes tag helps us know whether to back port or not and it also helps in reviewing the patch. Also get_maintainer.pl will CC the person who introduced the bug so they can review it. They are normally the best person to review their own code. Here it would be: Fixes: c5a8a8498eed ("ipvs: Fix uninit-value in do_ip_vs_set_ctl()") Which is strange... Also it suggest that the correct value is -EINVAL and not 0. The thing about uninitialized variable bugs is that Smatch and Clang both warn about them so they tend to get reported pretty quick. Apparently neither Nathan nor I sent forwarded this static checker warning. :/ regards, dan carpenter
