Julia Lawall 21195f8e9a coccinelle: deref_null: improve performance
Move rules looking for some special cases of safe dereferences before
the collection of NULL-tested values.  The special cases are fairly
rare, but somewhat costly to find, because isomorphisms create many
variants of the rules.  There is thus no need to search for them over
and over for each NULL tested expression.  Collecting them just once
is sufficient and more efficient.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
