    Subject[PATCH v7 5/9] bug.h: Fix BUILD_BUG_ON macro in __CHECKER__
    Date
    When __CHECKER__ is defined, we disable all of the BUILD_BUG.* macros.
    However, both BUILD_BUG_ON_NOT_POWER_OF_2 and BUILD_BUG_ON was
    evaluating to nothing in this case, and we want (0) since this is a
    function-like macro that will be followed by a semicolon.
