當我在OS X上克隆

Linux源代碼時,它們會立即被更改,并且git reset –hard不會將內容恢復.這是一個完整的會議：

$git clone git://github.com/torvalds/linux.git

$cd linux

$git status

On branch master

Your branch is up-to-date with 'origin/master'.

Changes not staged for commit:

(use "git add ..." to update what will be committed)

(use "git checkout -- ..." to discard changes in working directory)

no changes added to commit (use "git add" and/or "git commit -a")

我們可以看到,克隆后文件立即發生了變化.甚至不是他們的元數據,而是內容：

git diff include/uapi/linux/netfilter_ipv6/ip6t_HL.h

到底是怎么回事？為什么在克隆后立即修改文件？

總結
