Presumably there would be some way to specify, but file creation/deletion would be the most obviously useful events. > How would this be useful?

Does this mean we don't get told /what/ got created? Is an application that wants to know "what files are disappearing/appearing under /foo/bar/?" going to have to readdir() the whole directory every time it gets an event? > >How does it interact with unmounting the underlying filesystem? > > It will hold a reference to the 'vnode' of the file/directory in the kernel, > while we have the file events monitor on it.
