I think that there is a general problem about parse_size/parse_limit/str[x]ll functions... We should address all these issues with another set of patches. Your set of patches is big enough, and now we should stabilise them in order to be accepted. If we agree that it is not good thing to allow parse_limit to call exit(), I will leave parse_limit() as is. If you are brave enough ( :) ) add the /* Fallthrough */ comment and add the peta and exa cases. In the future we could move parse_limit in utils.c then implement parse_size in terms of parse_limits and finally replace all the occurrences of strto[x]ll... > > Thanks, > -Eric > > -- gpg @keyserver.linux.it: Goffredo Baroncelli (kreijackATinwind.it> Key fingerprint BBF5 1610 0B64 DAC6 5F7D 17B2 0EDA 9B37 8B82 E0B5 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
