mainlining shenanigans
616d9cee4f
When choosing a slot for an execbuffer, we ideally want to use the same address as last time (so that we don't have to rebind it) and the same address as expected by the user (so that we don't have to fixup any relocations pointing to it). If we first try to bind the incoming execbuffer->offset from the user, or the currently bound offset that should hopefully achieve the goal of avoiding the rebind cost and the relocation penalty. However, if the object is not currently bound there we don't want to arbitrarily unbind an object in our chosen position and so choose to rebind/relocate the incoming object instead. After we report the new position back to the user, on the next pass the relocations should have settled down.

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.
