With the introduction of requests, we amplified the number of atomic refcounted objects we use and update every execbuffer; from none to several references, and a set of references that need to be changed. We also introduced interesting side-effects in the order of retiring requests and objects. Instead of independently tracking the last request for an object, track the active objects for each request. The object will reside in the buffer list of its most recent active request and so we reduce the kref interchange to a list_move. Now retirements are entirely driven by the request, dramatically simplifying activity tracking on the object themselves, and removing the ambiguity between retiring objects and retiring requests. Furthermore with the consolidation of managing the activity tracking centrally, we can look forward to using RCU to enable lockless lookup of the current active requests for an object. In the future, we will be able to query the status or wait upon rendering to an object without even touching the struct_mutex BKL. All told, less code, simpler and faster, and more extensible. v2: Add a typedef for the function pointer for convenience later. v3: Make the noop retirement callback explicit. Allow passing NULL to the init_request_active() which is expanded to a common noop function.
