Yeah. There is the issue of you have a Fixes tag but can't figure out which commit the Fixes tag is referencing. And then there is the reverse where you backporting a patch and you want to see if there are any Fixes for that commit. Duplicated hashes messes up the search both ways. regards, dan carpenter
