I'm 100% with all others, thanks for having a look. On this one I can easily follow the argument of the fix for the newest release. But for stable we can never really know if there are users. In theory for anything that shipped in a Distribution someone might have coded and linked something against it - we would not know. The meant to be "stable" update will then break them the hard way. In this case gladly the function wasn't anything that one would consider useful for use from outside, so I think it is ok. But still I wanted to make the point that in general a symbol: 1. once released might be used and we can not never be sure if no one uses them 2. even being EXPERIMENTAL, touching them too much in stable updates means not-stable. Should we at least try to minimize the impact to stable releases? For now I'm adapting my checkers and will continue testing ... > There are updates to the libabigail.ignore for regex and gpu_dev to > ignore ABI changes for these fixes. > > -- > > I'm ok with changes above for 21.11.1, what do others think? > > Kevin. > > > > > Full log: > > https://launchpadlibrarian.net/596047842/buildlog_ubuntu-jammy-amd64.dpdk_21.11.1~rc1-0ubuntu1~jammyppa2_BUILDING.txt.gz > > > -- Christian Ehrhardt Staff Engineer, Ubuntu Server Canonical Ltd
