Linus Torvalds 81538c8e42 NFSD 6.18 Release Notes
Mike Snitzer has prototyped a mechanism for disabling I/O caching in
 NFSD. This is introduced in v6.18 as an experimental feature. This
 enables scaling NFSD in /both/ directions:
 
 - NFS service can be supported on systems with small memory
   footprints, such as low-cost cloud instances
 - Large NFS workloads will be less likely to force the eviction of
   server-local activity, helping it avoid thrashing
 
 Jeff Layton contributed a number of fixes to the new attribute
 delegation implementation (based on a pending Internet RFC) that we
 hope will make attribute delegation reliable enough to enable by
 default, as it is on the Linux NFS client.
 
 The remaining patches in this pull request are clean-ups and minor
 optimizations. Many thanks to the contributors, reviewers, testers,
 and bug reporters who participated during the v6.18 NFSD development
 cycle.
