Patch series "Optimize the fast path of mas_store()", v4. Add fast paths for mas_wr_append() and mas_wr_slot_store() respectively. The newly added fast path of mas_wr_append() is used in fork() and how much it benefits fork() depends on how many VMAs are duplicated. Thanks Liam for the review. This patch (of 4): Add tests for all cases of mas_wr_append() and mas_wr_slot_store().

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.
