The likely/unlikely profiler noticed that the unlikely statement in wb_domain_writeout_inc() is constantly wrong. This is due to the "not" (!) being outside the unlikely statement. It is likely that dom->period_time will be set, but unlikely that it wont be. Move the not into the unlikely statement.

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.
