Chuck,

While hunting for some bugs, I found some warts that the first two
patches clean up. I also added some sanity checks when freeing
delegations or queueing up a CB_RECALL. Your call on whether you want
to accept those. These should apply cleanly to your for-next branch,
but the last patch may need to be adjusted when Dai fixes up his patch.

Cheers,

Jeff Layton (4):
  nfsd: only fill out return pointer on success in nfsd4_lookup_stateid
  nfsd: fix comments about spinlock handling with delegations
  nfsd: make nfsd4_run_cb a bool return function
  nfsd: extra checks when freeing delegation stateids
