hrtimer_reprogram() must have access to the hrtimer_clock_base of the new first expiring timer to access hrtimer_clock_base.offset for adjusting the expiry time to CLOCK_MONOTONIC. This is required to evaluate whether the new left most timer in the hrtimer_clock_base is the first expiring timer of all clock bases in a hrtimer_cpu_base. The only user of hrtimer_reprogram() is hrtimer_start_range_ns(), which has a pointer to hrtimer_clock_base() already and hands it in as a parameter. But hrtimer_start_range_ns() will be split for the upcoming support for softirq based hrtimers to avoid code duplication and will lose the direct access to the clock base pointer. Instead of handing in timer and timer->base as a parameter remove the base parameter from hrtimer_reprogram() instead and retrieve the clock base internally.

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.
