In some cases we'd like to indicate the bitwise negation of a parameter,
e.g.
~@var
This will be helpful for describing the atomic andnot operations, where
we'd like to write comments of the form:
Atomically updates @v to (@v & ~@i)
Which kernel-doc currently transforms to:
Atomically updates **v** to (**v** & ~**i**)
Rather than the preferable form:
Atomically updates **v** to (**v** & **~i**)
This is similar to what we did for '!@var' in commit:
ee2aa75903 ("scripts: kernel-doc: accept negation like !@var")
This patch follows the same pattern that commit used to permit a '!'
prefix on a param ref, allowing a '~' prefix on a param ref, cuasing
kernel-doc to generate the preferred form above.

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.
