System/Linux/Mount.hsc:185:31: error:
    • Could not deduce (Num b) arising from the literal ‘0’
      from the context: (Enum a, Bits b)
        bound by the type signature for:
                   combineBitMasks :: (Enum a, Bits b) => [a] -> b
        at System/Linux/Mount.hsc:184:1-47
      Possible fix:
        add (Num b) to the context of
          the type signature for:
            combineBitMasks :: (Enum a, Bits b) => [a] -> b
    • In the second argument of ‘foldl’, namely ‘0’
      In the first argument of ‘(.)’, namely ‘foldl (.|.) 0’
