If the base clock is behind jiffies in the soft irq expiry code then the next timer is retrieved by get_next_timer_interrupt() to avoid incrementing base clock one by one. If the next timer interrupt is past current jiffies then the base clock is set to jiffies - 1. At the call site this is incremented and another iteration through the expiry loop is executed which checks empty hash buckets. That's a pointless excercise because it's already known that the next timer is past jiffies. Set the base clock in that case to jiffies directly so it gets incremented to jiffies + 1 at the call site resulting in immediate termination of the expiry loop.

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.
