I haven't seen emails before this one. But here are the only
three new NFSD commits in v6.1.71:

f9a01938e079 NFSD: fix possible oops when nfsd/pool_stats is closed.
bb4f791cb2de nfsd: call nfsd_last_thread() before final nfsd_put()
03d68ffc48b9 nfsd: separate nfsd_last_thread() from nfsd_put()

And the latter two are directly related to NFSD shut down.
