FWIW, I brought this up already at KS 2016, see Jon's coverage here: https://lwn.net/Articles/705220/ My primary motivation to bring that up back then was to try to reduce the number of patches that are taken into -stable while there is no good justification for that (by requiring each and every of those having Fixes: present as a requirement), but it didn't really lead anywhere. -- Jiri Kosina SUSE Labs
