If yes then it's missing a From line. > If not then the Signed-off-by should probably be changed to Acked-by or > Reviewed-by? So for now I'm assuming that the original patch was written by Mathieu, with modifications by you. So I added his From line and extended the SOB chain with the additional information that you modified the patch: Tested-by: Dietmar Eggemann Signed-off-by: Mathieu Poirier Signed-off-by: Juri Lelli [ Various additional modifications. ] Signed-off-by: Peter Zijlstra (Intel) Signed-off-by: Ingo Molnar Let me know if that's not accurate! Thanks, Ingo
