Thanks for telling. 

I cloned 0day-ci/linut to my local pc.
https://github.com/0day-ci/linux.git

However, I didn't find below branch. And tried to open it in web
broswer, also failed.

I did find a old one which is for the old version 5 post.

[bhe@...ux]$ git remote -v
0day-ci	https://github.com/0day-ci/linux.git (fetch)
0day-ci	https://github.com/0day-ci/linux.git (push)
[bhe@...p-128-28 linux]$ git branch -a| grep Baoquan| grep resource
  remotes/0day-ci/Baoquan-He/resource-Use-list_head-to-link-sibling-resource/20180612-113600

Could you help have a look at this?

Thanks
Baoquan
