[pnfs] Server Sessions

[Marc Eshel]

I am sure that you all see the same problem but though I will share what I 
get when trying to mount with pNFS enabled. Is there one bug that someone 
is trying to fix and than every thing will start working (except for 
callback) or there are multiple different problems with each call ? I am 
asking because I was wondering if we can share the work and debug the 
problems in parallel. One thing for sure we need to turn of those 
KERN_EMERG, they are pretty annoying. If no one objects I can take them 
out until I have something more useful to do.
Marc.
