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.
