====================
From: Alexei Starovoitov <ast@kernel.org>
The patch set is addressing a fallout from
commit 6fcd486b3a0a ("bpf: Refactor RCU enforcement in the verifier.")
It was too aggressive with PTR_UNTRUSTED marks.
Patches 1-6 are cleanup and adding verifier smartness to address real
use cases in bpf programs that broke with too aggressive PTR_UNTRUSTED.
The partial revert is done in patch 7 anyway.

============
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.
