I recently made the mistake of writing:
foo = lockdep_dereference_protected(..., lockdep_assert_held(...));
which is clearly bogus. If lockdep is disabled in the config this would
cause a compile failure, if it is enabled then it compiles and causes a
puzzling warning about dereferencing without the correct protection.
Wrap the macro in "do { ... } while (0)" to also fail compile for this
when lockdep is enabled.
