This sounds a lot like xfs simply filling up the directory index slots
of files that you just moved out with new files, and nfs falsely
claiming that this is a problem.
Any chance to figure out if the file you hit the printk with was one
that got either recently added or moved when you hit it? (I can't
follow the nfs code enough to check if it prints the first or second hit
of the same cookie)
