Changing field->is_signed to bool won't shrink the size of the struct. I prefer: field->is_signed = !!is_signed. >> >> + WARN_ON(offset >= (1 << 12)); >> + WARN_ON(size >= (1 << 12)); >> + WARN_ON(is_signed >= (1 << 1)); >> + WARN_ON(field->filter_type >= (1 << 4)); > > Note, the test for field->filter_type is wrong. > oops. > We should make a helper macro: > > #define VERIFY_SIZE(type) WARN_ON(type > field->type) > Much better! > and then have: > > VERIFY_SIZE(offset); > VERIFY_SIZE(size); > VERIFY_SIZE(filter_type); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
