I think there are only two strategies to maintain a backport which work in the long run: - insist on the simplest fixes and pure cherry-picks - or pick up _everything_ to sync up the two versions. The latter would mean a lot of commits - and I'm afraid it would also involve the scheduler header split-up, which literally involves hundreds of files plus perpetual build-breakage risk, so it's a no-no. > In my release of 4.9 - I'm planning on doing the simpler revert of 1b568f0aab > that introduced the performance degradation, rather than pulling in lots of > code > from newer kernels. That sounds much saner - I'd even Ack that approach for -stable as a special exception, than to complicate things with excessive backports. Thanks, Ingo
