====================
rxrpc: Fixes
Here is a collection of fixes for rxrpc:
(1) rxrpc_error_report() needs to call sock_error() to clear the error
code from the UDP transport socket, lest it be unexpectedly revisited
on the next kernel_sendmsg() call. This has been causing all sorts of
weird effects in AFS as the effects have typically been felt by the
wrong RxRPC call.
(2) Allow a kernel user of AF_RXRPC to easily detect if an rxrpc call has
completed.
(3) Allow errors incurred by attempting to transmit data through the UDP
socket to get back up the stack to AFS.
(4) Make AFS use (2) to abort the synchronous-mode call waiting loop if
the rxrpc-level call completed.
(5) Add a missing tracepoint case for tracing abort reception.
(6) Fix detection and handling of out-of-order ACKs.

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.
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.
