This short series passes the usual tests on NFSv4.0. We still do not
have a reproducer for the splat, though, so it's not known if the
issue has been fully addressed.

Because this is a long-standing issue and we do not have a
reproducer, I'm inclined to be conservative and push this in v5.19
rather than in v5.18-rc.

Thoughts, questions, and virtual rotten fruit welcome.

      NFSD: nfsd4_release_lockowner() should drop clp->cl_lock sooner
      NFSD: nfsd_file_put() can sleep
