Secure against (sensitive) mount options that contains , (comma)?

[johanot]

re: https://github.com/kubernetes/mount-utils/blob/master/mount_linux.go#L325

If mount options themselves contain a comma, it is possible for one mount option to be interpreted as multiple options.
This might be a problem especially for sensitive mount options that can cause leakages of sensitive values into logfiles.

e.g. password=my,passw0rd will give an error like: "Invalid mount option passw0rd" in the kernel log (denpeding on the mount driver)

This issue might be out of scope for this library to handle, since fs-drivers (afaik, correct me?) behave differently and some might allow escaping of mount options with backslash while others might not. So I'm fine with this being closed as: "up to the implementer to guard against" - as long as that's a conscious decision.
