从上找到的一个配置脚本，下载后添加可执行权限，然后运行即可。
下面是脚本setup-msmtp-for-gmail.sh的内容

点击"allowing access to less secure apps"，然后打开i如下设置：
然后即可以用git send-email提交kernel补丁了：（可以参考和分享给大家的资料， 或点）
1、配置git send-email如下（.gitconfig）
[sendemail] smtpserver = /usr/bin/msmtp
2、生成patch
git format-patch -1
比如生成的patch是： 0001-ASoC-compress-Set-reasonable-compress-id-string.patch
如果需要一次生成多个patch的话，使用下面的命令：
git format-patch -s -n --cover-letter --thread
3、检查patch
./scripts/checkpatch.pl 0001-ASoC-compress-Set-reasonable-compress-id-string.patch
4、获得maintainer
./scripts/get_maintainer.pl 0001-ASoC-compress-Set-reasonable-compress-id-string.patch
5、提交
git send-email --to xx@xx --to xx@xx --cc xx@xx --cc xx@xx 0001-ASoC-compress-Set-reasonable-compress-id-string.patch
如果提交的是一些列patch的话，将这些patch在一个git send-email中发送。
完。
