Typical in automated builds, old example: https://groups.google.com/a/chromium.org/d/msg/chromium-os-dev/zxOa0OLWFkw/N_Sb7EZOBwAJ Here's a more complex but faster and more transparent way to test Mike's fix than copying an entire tree: # Make sure you start from a clean state git describe --dirty # must not -dirty make prepare # Simulate a copy of the tree but with just one file rsync --perms --times README README.mtime_backup rm README rsync --perms --times README.mtime_backup README stat README README.mtime_backup # Demo the BUG fixed by Mike ./scripts/setlocalversion # -dirty BUG! because spurious inode ctime difference git diff-index HEAD git describe --dirty # not -dirty ./scripts/setlocalversion # not -dirty any more cause describe refreshed index # Make sure mtime still causes -dirty with AND without Mike's fix touch README ./scripts/setlocalversion # -dirty -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
