The commit *relaxed* sparse behavior: because previously sizeof(bool) was an error. I'm not in favor of any diagnostic at all for sizeof(bool), but my recollection is that a sparse maintainer wanted it to yield one. I don't care about the particular result for sizeof(bool) as long as it matches the ABI. -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
