This implements a sequence number cache of the last three (right now hardcoded) sent sequence numbers for a given XID, as suggested by the RFC. From RFC2203 5.3.3.1: "Note that the sequence number algorithm requires that the client increment the sequence number even if it is retrying a request with the same RPC transaction identifier. It is not infrequent for clients to get into a situation where they send two or more attempts and a slow server sends the reply for the first attempt. With RPCSEC_GSS, each request and reply will have a unique sequence number. If the client wishes to improve turn around time on the RPC call, it can cache the RPCSEC_GSS sequence number of each request it sends. Then when it receives a response with a matching RPC transaction identifier, it can compute the checksum of each sequence number in the cache to try to match the checksum in the reply's verifier."

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.
