To track the changes in hyperv related files I created some scripts years ago to automate the process of finding relevant commits in linux.git. Part of that process is to record the tag when a commit appeared in mainline. This worked fine, until very recently. Suddenly years-old commits are declared as having-just-arrived in linux.git. Look at this example: $ git log --oneline -- drivers/input/serio/hyperv-keyboard.c 2048157 Drivers: hv: vmbus: fix the building warning with hyperv-keyboard 62238f3 Input: hyperv-keyboard - register as a wakeup source c3c4d99 Input: hyperv-keyboard - pass through 0xE1 prefix aed06b9 Input: add a driver to support Hyper-V synthetic keyboard $ git describe --contains aed06b9 v4.6-rc1~9^2~792 $ git show aed06b9 | head commit aed06b9cfcabf8644ac5f6f108c0b3d01522f88b Author: K. Y. Srinivasan <kys@xxxxxxxxxxxxx> Date: Wed Sep 18 12:50:42 2013 -0700 Obviously that and other commits are in the tree since a very long time. How can I find out whats going on? Is my git(1) 2.8.1 broken, or did Linus just pull some junk tree (and does he continue to do so)?
