It boils down to giving more information to the underlying implementation with hope that it can be useful for something. Although at this point I think strncmp vs strcmp vs memcmp may be not worth doing (we keep explicit length comparison to reduce *cmp calls though). The gain is relatively small and will become even smaller after we avoid running exclude on tracked files (which eliminates like 2/3 of the processed entries). -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
