This patch adds static trace for RNRNAK timer. Currently the output from hrtimer static trace only shows the addresses of hrtimers in the system and there is no easy way to correlate an RNRNAK timer with its entries in the hrtimer trace. This patch adds the correlation among a QP, its RNRNAK timer, and its entries in the hrtimer trace. This correlation will be enormously helpful when debugging RNRNAK related issues. In addition, this patch cleans up rvt_stop_rnr_timer() to be void while here.

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.
