So, I\'m confused as to what\'s going on. I\'ve never hacked on the linux kernel, so maybe this is commonplace. If that\'s the case, sorry for the newb question.
One thing you can try is git update-index --refresh in case somehow the cache of filestat information got wonked in the process of cloning (maybe by an ntpd clock adjustment or such?). If that doesn't help, we'll probably need to know what the output of git diff looks like to help you more.
