Back in the dim distant past, the task_struct structure's RCU-related fields optionally included those needed for CONFIG_RCU_BOOST, even in CONFIG_PREEMPT_RCU builds. The INIT_TASK_RCU_TREE_PREEMPT() macro was used to provide initializers for those optional CONFIG_RCU_BOOST fields. However, the CONFIG_RCU_BOOST fields are now included unconditionally in CONFIG_PREEMPT_RCU builds, so there is no longer any need fro the INIT_TASK_RCU_TREE_PREEMPT() macro. This commit therefore removes it in favor of initializing the ->rcu_blocked_node field directly in the INIT_TASK_RCU_PREEMPT() macro. 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.
