Thanks Owen. Good to know about the keyhole/shield icons. The filter function doesn't work as well as I hoped. The shield icons that matched my username in CODEOWNERS are BOLD while the others are a bit greyed out;
Using that I was able to identify a few files that matched line 28 in CODEOWNERS. #28: geode-core/**/org/apache/geode/internal/* @bschuchardt @Bill @kirklund So that explains why I was added as a reviewer. Thanks
