Hi Dave,

Looking at the XFS code in general we do tend to prefix XFS specific macro 
with XFS_ . I did hit the name conflict with one of our internal module I 
did fix our module to prefix with the module name but I thought since I did 
hit the problem that maybe other people might have the same issue. This is 
why I am proposing this mod. it is low priority but I find it is a little 
cleaner to have this prefix.

Hope this make sense.

Alain
