No, the XFS guys had to work around the differences between the Linux vm 
and IRIX's and that eventually led to what we have today - a big messy 
pile of code. It would be no surprise for there to be stuff that get 
triggered imho.

I am not saying that XFS itself is bad. Just that the implementation on 
Linux was not quite the same quality as it is on IRIX.
