I did some work on realtime a month or so ago, to get basic
functionality working again. So it basically seems to work, but it has not
had heavy testing. Basically the same as before, I guess. It is
probably about time to start spending some time on this feature.
In terms of using it for a production site, (when it is supported),
that depends on what you want to do. It would be appropriate for something
like video streams, for example. The main difference is that it allocates
in larger (potentially quite large) chunks, and has a more deterministic
allocator. All realtime writes are also done with O_DIRECT (direct I/O)
and some xfs-specific userspace calls, so your app would have to support
it.
