This patch adds tags __not_msg(<msg>) and __not_msg_unpriv(<msg>). Test fails if <msg> is found in verifier log. If __msg_not() is situated between __msg() tags framework matches __msg() tags first, and then checks that <msg> is not present in a portion of a log between bracketing __msg() tags. __msg_not() tags bracketed by a same __msg() group are effectively unordered. The idea is borrowed from LLVM's CheckFile with its CHECK-NOT syntax.

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.
