There is nothing in Tiger/Darwin 8 to generate kevents at the VFS
layer. But that is being worked on for a future release. When it
arrives, network filesystems will have locally-driven changes auto-
reflected into the kevent/knote system. They will also have a way to
be informed when someone is watching a file locally so they can
subscribe to whatever remote event system their protocol might
support and then reflect remote changes into the kevent system as well.

Since the knote interface is no longer public, does this mean that
knotes are auto-generated by the kernel? This is for a local file
system, but I'd be interested the status for network file systems too.
I had a quick look at the VFS source and didn't see anything to
suggest this is the case, but thought maybe the new kernel event
system generated corresponding knotes. Then again, both HFS and UFS
still generate their own notes...
If knotes are not auto-generated, is there a way for VFS plugins to
do so while still remaining KPI compliant?
Knotes and byte-range locking (vfs_setlocklocal) seem to be some
rather big oversights in the KPI.
