      nfsd: common grace period control · af558e33
      J. Bruce Fields authored
      Rewrite grace period code to unify management of grace period across
      lockd and nfsd.  The current code has lockd and nfsd cooperate to
      compute a grace period which is satisfactory to them both, and then
      individually enforce it.  This creates a slight race condition, since
      the enforcement is not coordinated.  It's also more complicated than
      Here instead we have lockd and nfsd each inform common code when they
      enter the grace period, and when they're ready to leave the grace
      period, and allow normal locking only after both of them are ready to
      We also expect the locks_start_grace()/locks_end_grace() interface here
      to be simpler to build on for future cluster/high-availability work,
      which may require (for example) putting individual filesystems into
      grace, or enforcing grace periods across multiple cluster nodes.
