Re: [take 3] Use pid in inotify events.

I have a network server, which gets IO requests from different clients

notifications about events, but there is no way to determine if given IO
was originated by server itself (and in this case nothing should be
done), or by external application which accesses exported directory (and
in this case I should send update messages to clients).

Why not require local access to use the same mechanism as remote, i.e.
by "network mounting" the data on the local machine, too.  That way
there's no confusion over where the change originated nor who's copy
must be invalidated.
