我是git add git\的整个文件夹
然后修改git\drivers下的Makefile文件
运行git status 如下:
# 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)
# (commit or discard the untracked or modified content in submodules)
#
# modified: git/drivers (modified content, untracked content)
