There are two different tasks to do: - speed up stat by providing a subset of the information - provide a mechanism to get arbitrary attribute support and efficient ways to get to it Trying to force both of these tasks into one interface will partially defeat the purpose of the first, creating a fast stat replacement. I think these should be different interfaces (if the second type is needed at all). As for making the interface extendable. In all the years there hasn't really been much need to extend the stat structure (ignoring extended attributes). So, I'd not be worried about using a simple 32-bit bitmask to select the fields to include in the fast stat. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
