Functions

func IsMountFS

func IsMountFS(mntType int64, path string) (bool, bool, error)

IsMountFS returns two boolean values, checking

• whether the path is a mount point;
• if yes, whether its filesystem type is mntType.

Note that this function can not detect bind mounts, and is not working properly when path="/".
