Well, I have reason to believe they were. I'm going off of reading and 
stuff I remember early-middle of last year or before. So the development 
was at the very least going on.

Well, that was the reason I remember reading for the vfs overhaul. SGI 
made alot more information in terms of I/O tuning and monitoring and 
dumping of misc bits than Linux 2.4. Because of this, a bunch of crap was 
modified in the 2.4 fs layer to accomodate proper running of XFS, 
and subsequently provided much more useful interfaces to the other high 
performance filesystems on linux. In all it was supposed to be a damn good 
upgrade.

Even if XFS isn't shipped with the 2.6 kernel (which would suck), I think 
the fs improvements are supposed to be there. And it may just show up in 
one of the later 2.6 point releases.
