func FindSysFsDevice ¶

func FindSysFsDevice(dev string) (string, error)

FindSysFsDevice for given argument returns physical device where it is linked to. For device nodes it will return path for device itself. For regular files or directories this function returns physical device where this inode resides (storage device). If result device is a virtual one (e.g. tmpfs), error will be returned. For non-existing path, no error returned and path is empty.

func (*Hint) String ¶

func (h *Hint) String() string

String returns the hints as a string.

type Hints ¶

type Hints map[string]Hint

Hints represents set of hints collected from multiple providers

func MergeTopologyHints ¶
