Benny hi
Please push your new tree with below patch and I will
send you SQUASHMES ontop of your tree. This is because
I'm having problems making a coherent tree, because
current pnfs/pnfsd-exofs branch has conflicts when
merging with 3.1-rc1. So your rebase should save me the
resolving work.
Thanks
Boaz
