As we require valid start/end parameters, we can replace the initial potential NULL with a pointer to the drm_mm.head_node and so reduce the test on every iteration from a NULL + address comparison to just an address comparison. add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-26 (-26) function old new delta i915_gem_evict_for_node 719 693 -26 (No other users outside of the test harness.)

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.
