4.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Heinz Mauelshagen <[email protected]> commit 880bcce0dcc3172fe865352b492c41d85290cb8d upstream. Fix a race for "nosync" activations providing "aa.." device health characters and "0/N" sync ratio rather than "AA..." and "N/N". Occurs when status for the raid set is retrieved during resume before the MD sync thread starts and clears the MD_RECOVERY_NEEDED flag.
