I am afraid that the CI failed. Please help to take a look. @houstar @zjumoon01

I am wondering if the following result is related:

Makefile:84: recipe for target 'localrootlessintegration' failed
make: *** [localrootlessintegration] Error 1
make[1]: *** [rootlessintegration] Error 2
make[1]: Leaving directory `/home/travis/gopath/src/github.com/opencontainers/runc'
make: *** [test] Error 2
The command "make BUILDTAGS="${BUILDTAGS}" clean ci cross" exited with 2.

I see the CI has been failed since commit cb0fd7d on branch develop due to the same error.
@Ace-Tang , could you please have a check together ?

I fix the ci fail with develop branch, fail because PR #12, it get some extend cgroup interface, it can not work with runc v1.0.0-rc6.
This PR need rebase on new develop branch
