During execbuf, a mandatory step is that we add this request (this fence) to each object's reservation_object. Inside execbuf, we track the vma, and to add the fence to the reservation_object then means having to first chase the obj, incurring another cache miss. We can reduce the number of cache misses by stashing a pointer to the reservation_object in the vma itself.

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.
