The print_other_cpu_stall() function currently unconditionally invokes rcu_print_detail_task_stall(). This is OK because if there was a stall sufficient to cause print_other_cpu_stall() to be invoked, that stall is very likely to persist through the entire print_other_cpu_stall() execution. However, if the stall did not persist, the variable ndetected will be zero, and that variable is already tested in an "if" statement. Therefore, this commit moves the call to rcu_print_detail_task_stall() under that pre-existing "if" to improve readability, with a very rare reduction in overhead.

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.
