The debugfs interface displayed statistics on RCU-pending checks but this interface has since been removed. This commit therefore removes the no-longer-used rcu_data structure's ->n_rcu_pending, ->n_rp_core_needs_qs, ->n_rp_report_qs, ->n_rp_cb_ready, ->n_rp_cpu_needs_gp, ->n_rp_gp_completed, ->n_rp_gp_started, ->n_rp_nocb_defer_wakeup, and ->n_rp_need_nothing fields along with their updates. If this information proves necessary in the future, the corresponding event traces will be added. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
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.
