This commit adds a test for a three-level srcu_node tree for Tree SRCU in the existing SRCU-P scenario. This requires enabling CONFIG_RCU_EXPERT, so the CONFIG_RCU_EXPERT=n scenario is now SRCU-N. The reason for using SRCU-P for the tall tree is that preemption raises the possibility of locating more bugs than does the non-preemptive SRCU-N. Signed-off-by: Paul E.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
