The cost of adding a syscall is much smaller than adding all the wanking in your system call. Think about it - adding a new stat variant if a few lines of code which add minimal icache footpint. Even less so when the applications using the old ones disappear for a while. Totally overdesigned crap like yours on the other hand adds lots of code and branches that stay forever. In addition to making life for strace and co really hard if the structure ever changes. So adding a few fields of padding at the end for new members is fine, but doing overkill of versioning including queries for supported versions doesn't. -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
