Linux kernel sources changed to OSX immediately after cloning

Question

When I cloned Linux sources on OS X, they change immediately, and git reset --hardnot return the contents. Here's the full session:

$ 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 <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

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

As we can see, the files were changed immediately after cloning. And even their metadata, but the contents:

System Information:

• File System: Registered HFS +
• Operating System: OS X 10.11.5 (15F34)
• git version: 2.9.0
• ~/.gitconfigonly has a [user]record.

What's happening? Why were the files changed right after cloning?
