This updates vendored runc/libcontainer to 1.1.0, and google/cadvisor to a version updated to runc 1.1.0 (google/cadvisor#3048). Changes in vendor are generated by (roughly): ./hack/pin-dependency.sh github.com/google/cadvisor v0.44.0 ./hack/pin-dependency.sh github.com/opencontainers/runc v1.1.0 ./hack/update-vendor.sh ./hack/lint-dependencies.sh # And follow all its recommendations. ./hack/update-vendor.sh ./hack/update-internal-modules.sh ./hack/lint-dependencies.sh # Re-check everything again.
