Fixes: is a "best effort if we get around to it because a maintainer forgot to put an actual cc: stable tag on it". As the documentation has stated, since the start of the stable kernel tree work, use a cc: stable tag if you want it to go to a stable tree. Fixes came years later and we are forced to dig through them occasionally because people forget. But you do NOT get a FAILED email if the commit does not apply to a stable tree, and sometimes we just ignore them entirely if we are busy with other stuff. So please ALWAYS use cc: stable@ on patches you know you want to be applied to stable trees. Use the Fixes: tag to tell us how far back to backport them. That's it. Use both. thanks, greg k-h
