/**
* static_assert - check integer constant expression at build time
*
* static_assert() is a wrapper for the C11 _Static_assert, with a
* little macro magic to make the message optional (defaulting to the
* stringification of the tested expression).
*
* Contrary to BUILD_BUG_ON(), static_assert() can be used at global
* scope, but requires the expression to be an integer constant
* expression (i.e., it is not enough that __builtin_constant_p() is
* true for expr).
*
* Also note that BUILD_BUG_ON() fails the build if the condition is
* true, while static_assert() fails the build if the expression is
* false.
