In the next commits, we may not evict when refcount = 0. igt_vm_isolation() continuously tries to pin/unpin at same address, but also calls put() on the object, which means the object may not be unpinned in time. Instead of this, re-use the same object over and over, so they can be unbound as required. Changes since v1: - Fix cleaning up obj_b on failure.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
