The rcu_print_detail_task_stall(), rcu_print_task_stall_begin(), and rcu_print_task_stall_end() functions were defined to allow long-gone Kconfig options to provide an abbreviated RCU CPU stall warning printout. This commit saves a few lines of code by inlining them into their sole callers. While in the area, a useless call of rcu_print_detail_task_stall_rnp() on the root rcu_node structure was eliminated. If there is only one rcu_node structure, its tasks get printed twice, but if there are more, the root rcu_node structure is guaranteed to have an empty list of blocked tasks, hence the uselessness. (Long ago, root rcu_node structures with non-empty ->blkd_tasks lists could happen, but no longer.) Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com> |

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.
