如何使用git 生成patch

1,下载代码
Git clone git://git.kernel.org/pub/scm/Linux/kernel/git/padovan/bluetooth-next-2.6.git
cd bluetooth-next-2.6
2,修改代码
vi drivers/bluetooth/btusb.c
3,把代码添加到git管理仓库
git add drivers/bluetooth/btusb.c
4,提交修改
git commit -m "Added atheros3012 Chip Firmware download support"
5,查看日志
git log <== to git the previous commit hash code.
6,生成patch
git format-patch -s 1bbe3c8c197a35f79bfddaba099270a2e54ea9c7
please replace the hash code with your repo previous commit.
then you can find the patch under repo directory.
then mail your patch to configuration admin. 
或者使用
git format-patch HEAD^ <==最近的1次commit的patch
git format-patch HEAD^^ <==最近的2次commit的patch
git format-patch HEAD^ <==最近的3次commit的patch
git format-patch HEAD^ <==最近的4次commit的patch
git format-patch HEAD^^^^^ <==不支持！！！！error！！！
 
7,退回去
git reset --hard 1bbe3c8c197a35f79bfddaba099270a2e54ea9c7
 
8.将补丁打上去。
patch -p1 < 0001-Added-liuxingde-test.patch
注： 0001-Added-liuxingde-test.patch为想要打的补丁的名字。运行该命令需在git项目的要目录下。
