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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
