[ Upstream commit 5326a18e3e ]
Rust Binder exposes information about transactions that are sent in
various ways: printing to the kernel log, tracepoints, files in
binderfs, and the upcoming netlink support. Currently all these
mechanisms use disparate ways of obtaining the same information, so
let's introduce a single Info struct that collects all the required
information in a single place, so that all of these different mechanisms
can operate in a more uniform way.
For now, the new info struct is only used to replace a few things:
* The BinderTransactionDataSg struct that is passed as an argument to
several methods is removed as the information is moved into the new
info struct and passed down that way.
* The oneway spam detection fields on Transaction and Allocation can be
removed, as the information can be returned to the caller via the
mutable info struct instead.
But several other uses of the info struct are planned in follow-up
patches.

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.
