For use cases where you are exposing metadata from the host to the guest
this would be a very convenient approach indeed. As asked elsewhere in this
thread, my main thought would be about how well it suits a application that
wants a generic stream based connection between host & guest ?
Efficient integration into a poll(2) based event loop would be key to
that.
You mean for a very large number of files (determining which property
has changed?).
I think what Daniel means is that for file to have stream semantic it is
not enough to ignore offset on read/write, but poll also should behave
similar to how it behaves with char device fd. With regular files poll
will always report that fd is ready for I/O.
I'm not really sure, but given the 9P protocol, I suspect it would have
to. Eric?
