====================
rxrpc: Development
Here are some development patches for AF_RXRPC. The most significant points
are:
(1) Change the tracepoint that indicates a packet has been transmitted
into one that indicates a packet is about to be transmitted. Without
this, the response tracepoint may occur first if the round trip is
fast enough.
(2) Sort out AFS address list handling to better enforce maximum capacity
to use helper functions to fill them and to do an insertion sort to
order them. This is here to make (3) easier.
(3) Keep AF_INET addresses as AF_INET addresses rather than converting
them to AF_INET6 in both AF_RXRPC and kAFS. I hadn't realised that a
UDP6 socket would just call down into UDP4 if given an AF_INET
address.
(4) Allow the timestamp on the first DATA packet of a reply to be
retrieved by a kernel service. This will give the kAFS a more
accurate base from which to calculate the callback promise expiration.
(5) Allow the rxrpc protocol epoch value to be retrieved from an incoming
call. This will allow kAFS to determine if the fileserver restarted
and if two addresses apparently assigned to the same fileserver
actually are different boxes.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
