The notify API needs the ability to report, in general, whether you'll get notify events from a particular filesystem / file / directory / whatever-condition anyway. And also whether you get events for all (remote) changes, or just local changes. You might as well _try_ to get a delegate, and if you fail, tell the caller that it won't receive notifications on this file and will have to poll - just like most other remote filesystems. -- Jamie -- 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
