Or rather it is used only by intel_ring_pin() to extract the drm_i915_private which we can easily pass in. As this is a relatively rare operation, save the space in the struct, and as such it is even break even in the extra code for passing around the parameter: add/remove: 0/0 grow/shrink: 2/3 up/down: 15/-15 (0) function old new delta intel_init_ring_buffer 906 918 +12 execlists_context_pin 1308 1311 +3 mock_engine 407 403 -4 intel_engine_create_ring 367 363 -4 intel_ring_pin 326 319 -7 Total: Before=1261794, After=1261794, chg +0.00% v2: Reorder intel_init_ring_buffer to keep the ring setup together: add/remove: 0/0 grow/shrink: 2/3 up/down: 9/-15 (-6) function old new delta intel_init_ring_buffer 906 912 +6 execlists_context_pin 1308 1311 +3 mock_engine 407 403 -4 intel_engine_create_ring 367 363 -4 intel_ring_pin 326 319 -7 Total: Before=1261794, After=1261788, chg -0.00% Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170403113426.25707-1-chris@chris-wilson.co.uk |

README
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.
