Exactly right. > Was there something wrong with them that they would not go into 4.11? They were submitted way too late. * The merge window opened on Sunday, 19th February. * The patches were submitted on Thursday, 16th February just before 6pm my local time. * The last linux-next grab of trees before the merge window happened occured around 11pm my local time on Thursday, 16th February. There's a general requirement that everything for a merge window should be in linux-next before the merge window. I generally want material for the merge window to be ready a week before the merge window opens to allow for proper testing and any re-work that comes out of that testing. In any case, anything submitted from Thursday through to the Sunday when the merge window opens _definitely_ is not going to get queued for the merge window unless there are exceptional (eg, important bug fix) reasons to do so. So, it basically missed the time slot for merging new material, sorry. I'll re-open my tree for new material in the next few days. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
