/// Please, don't reintroduce uninitialized_var().
///
/// From Documentation/process/deprecated.rst,
/// commit 4b19bec97c88 ("docs: deprecated.rst: Add uninitialized_var()"):
///  For any compiler warnings about uninitialized variables, just add
///  an initializer. Using warning-silencing tricks is dangerous as it
///  papers over real bugs (or can in the future), and suppresses unrelated
///  compiler warnings (e.g. "unused variable"). If the compiler thinks it
///  is uninitialized, either simply initialize the variable or make compiler
///  changes. Keep in mind that in most cases, if an initialization is
///  obviously redundant, the compiler's dead-store elimination pass will make
///  sure there are no needless variable writes.
///
/// Later, commit 3942ea7a10c9 ("deprecated.rst: Remove now removed
/// uninitialized_var") removed this section because all initializations of
/// this kind were cleaned-up from the kernel. This cocci rule checks that
/// the macro is not explicitly or implicitly reintroduced.
