srcu: Reduce scans of srcu_data in counter wrap check
Currently, given a multi-level srcu_node tree, SRCU can scan the full set of srcu_data structures at each level when cleaning up after a grace period. This, though harmless otherwise, represents pointless overhead. This commit therefore eliminates this overhead by scanning the srcu_data structures only when traversing the leaf srcu_node structures.

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.
