But I think that a change attribute is potentially an *extremely* useful thing, and for more than just nfs servers. Lots of userspace programs also need to know whether a file has changed since they last examined it, and also suffer from the limitations of using ctime or mtime as an imperfect approximation to a real change attribute. But it would make sense to split the user space changes into a second patch and possibly apply it later. --b. - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
