6bab69c65013be Rasmus Villemoes 2019-03-07  64   * static_assert() is a wrapper 
for the C11 _Static_assert, with a
6bab69c65013be Rasmus Villemoes 2019-03-07  65   * little macro magic to make 
the message optional (defaulting to the
6bab69c65013be Rasmus Villemoes 2019-03-07  66   * stringification of the 
tested expression).
6bab69c65013be Rasmus Villemoes 2019-03-07  67   *
6bab69c65013be Rasmus Villemoes 2019-03-07  68   * Contrary to BUILD_BUG_ON(), 
static_assert() can be used at global
6bab69c65013be Rasmus Villemoes 2019-03-07  69   * scope, but requires the 
expression to be an integer constant
6bab69c65013be Rasmus Villemoes 2019-03-07  70   * expression (i.e., it is not 
enough that __builtin_constant_p() is
6bab69c65013be Rasmus Villemoes 2019-03-07  71   * true for expr).
6bab69c65013be Rasmus Villemoes 2019-03-07  72   *
6bab69c65013be Rasmus Villemoes 2019-03-07  73   * Also note that 
BUILD_BUG_ON() fails the build if the condition is
6bab69c65013be Rasmus Villemoes 2019-03-07  74   * true, while static_assert() 
fails the build if the expression is
