ErrNoCFSLimit is no quota limit

var ErrNoCFSLimit = errors.Errorf("no quota limit")

func ParseUintList

func ParseUintList(val string) (map[int]bool, error)

ParseUintList parses and validates the specified string as the value found in some cgroup file (e.g. cpuset.cpus, cpuset.mems), which could be one of the formats below. Note that duplicates are actually allowed in the input string. It returns a map[int]bool with available elements from val set to true. Supported formats: 7 1-6 0,3-4,7,8-10 0-0,0,1-7 03,1-3 <- this is gonna get parsed as [1,2,3] 3,2,1 0-2,3,1

func ReadStat
