[PATCH 1/4] drm/mm: add "best_match" to drm_mm_insert_node()

David Herrmann dh.herrmann at gmail.com
Thu Jul 25 06:55:59 PDT 2013


Add a "best_match" argument similar to the drm_mm_search_*() helpers so we
can convert TTM to use them in follow up patches. We can also inline the
non-generic helpers and move them into the header to allow compile-time
optimizations.
