Full testing of the new SRCU polling API requires that the fake writers also use it in order to test concurrent calls to all of the API members, especially start_poll_synchronize_srcu(). This commit prepares the ground for this by making the synctype[] and nsynctype variables be static globals so that the rcu_torture_fakewriter() function can access them. Initialization of these variables is moved from rcu_torture_writer() to a new rcu_torture_write_types() function that is invoked from rcu_torture_init() just before the first writer kthread is spawned.

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.
