我把linux上的spdk 代码 copy到windows上后， 用git extension打开后发现有300 多个文件有改动， 但是用diff tool看， 显示完全一样。
在window上用git bash 看时，
git status 显示如下：

实际这文件 没有改动，
解决办法如下， 同一个路径下执行：‘
git config --add core.filemode false
这个时候再查：
Administrator@XTZJ-20220917LC MINGW64 /e/1_study/1_dpdk/spdk_practice/spdk (dev/bob-1.x)
$ git status
On branch dev/bob-1.x
Changes not staged for commit:(use "git add <file>..." to update what will be committed)(use "git restore <file>..." to discard changes in working directory)(commit or discard the untracked or modified content in submodules)modified: dpdk (modified content)modified: intel-ipsec-mb (modified content)modified: isa-l (modified content)modified: isa-l-crypto (modified content)modified: libvfio-user (modified content)modified: ocf (modified content)modified: xnvme (modified content)no changes added to commit (use "git add" and/or "git commit -a")
这个时候 发现， 没有改动文件 已经不显示 了。
