The canonical reasons I've heard are 1) they don't want to spend the money/time/resources to acquire enough XFS expertise to support it at the Enterprise level
I could think of 2 guys they could easily snatch away from SGI that could bring such experience -- pretty much the 2 behind much of the VFS in kernel 2.6 anyway (so great resources regardless).
The main argument I can see is "clean upgrade path". XFS doesn't offer anything hugely compelling over ext3 -- which is, after all, very flexible and extensible. And Red Hat already *has* Stephen Tweedie.
Feature-wise, probably not. The VFS in 2.6 brings a lot of former XFS-only features to _all_ filesystems. But I still see serious size limitations as well as scalability to Ext3 versus XFS.
Serious in some cases; not in the general case. Given the above, there has to be something *widespread* that ext3 just *can't* do.
