Hi David,

Could you please retest using the patches that are currently in my
'devel' git branch?

git pull git://git.linux-nfs.org/projects/trondmy/linux-nfs.git devel

They fix up a number of minor issues with the delegation code,
specifically ones that might cause a delegation to be removed
prematurely.

Thanks!
  Trond
