XFS With Linux 6.13 Sees Major Rework To Real-Time Volumes

Depends on what you mean by "this". If you mean the pull request in the article, I have no idea what it is all touching. If you mean XFS real time devices as a thing, no: XFS RT devices hold data and metadata.

Sure, it holds both. But the above Oracle link makes it sound like only metadata is handled differently from normal XFS.

That's because XFS-RT is concerned with metadata write determinism (it specifically creates space allocations in deterministic fashion to be sure the data is written in defined time slices - this is part of file metadata, not the data itself). It's not specifically about the data in the file itself. I think there's very few people to this day realize just how potent metadata consistency and accuracy is in certain situations. Not in spying on people, but reconstructing past events accurately, and managing concurrency and/or race conditions. Average desktop users can ignore this. Certain problem domains can't.
