In TEST_ONLY commit, rm global_state will duplicate the object and request for new reservations, once they pass then the new state will be swapped with the old and will be available for the Atomic Commit. This patch fixes some of missing links in the resource reservation sequence mentioned above. 1) Creation of duplicate state in test_only commit (Rob) 2) Allocate and release the resources on every modeset. 3) Avoid allocation only when active is false. In a modeset operation, swap state happens well before disable. Hence clearing reservations in disable will cause failures in modeset enable. Allow reservations to be cleared/allocated before swap, such that only newly committed resources are pushed to HW. Changes in v1: - Move the rm release to atomic_check. - Ensure resource allocation and free happens when active is not changed i.e only when mode is changed.(Rob) Changes in v2: - Handle dpu_kms_get_global_state API failure as it may return EDEADLK (swboyd).

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.
