There are separate issues here. XFS was designed according to a
``think big'' principle (e.g. deal with terabytes of storage and
hundreds of MBs/sec I/O speeds). But XFS as a filesystem doesn't know
about all the disk array muck that makes this possible (e.g. striping
or concatenation) -- there's a separate subsystem (XLV) for that.
Second, if you are not as big as XFS expects then you may not want
that bloat.
Finally, XFS is tainted. I believe this is what is holding up the
release; SGI needs to clean the code of any tainted parts and
reimplement these parts under the GPL before it can release the code.
P.S. Do you remember more specifics about this VM integration stuff?
AFAIK, this is relevant only to `direct I/O' XFS property.
