This function is not very efficient, does not really belong to cgroup package, and is only used once (from fs/cpuset.go). Prepare to remove it by replacing with the implementation based on the parser from github.com/moby/sys/mountinfo parser. This commit is here to make sure the proposed replacement passes the unit test. Funny, but the unit test need to be slightly modified since it supplies the wrong mountinfo (space as the first character, empty line at the end). Validated by $ go test -v -run Ance === RUN TestGetClosestMountpointAncestor --- PASS: TestGetClosestMountpointAncestor (0.00s) PASS ok github.com/opencontainers/runc/libcontainer/cgroups 0.002s Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
