Linus Torvalds b6dde1e527 NFSD 6.15 Release Notes
Neil Brown contributed more scalability improvements to NFSD's
 open file cache, and Jeff Layton contributed a menagerie of
 repairs to NFSD's NFSv4 callback / backchannel implementation.
 
 Mike Snitzer contributed a change to NFS re-export support that
 disables support for file locking on a re-exported NFSv4 mount.
 This is because NFSv4 state recovery is currently difficult if
 not impossible for re-exported NFS mounts. The change aims to
 prevent data integrity exposures after the re-export server
 crashes.
 
 Work continues on the evolving NFSD netlink administrative API.
 
 Many thanks to the contributors, reviewers, testers, and bug
 reporters who participated during the v6.15 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.
