This isn't actually protecting anything becuase: - when running, ttm_resource_manager->use_type is protected through vmw_private->reservation_semaphore against concurrent execbuf or well anything else that might evict or reserve buffers - during suspend/resume there's nothing else running, hence vmw_pm_freeze and vmw_pm_restore do not need to take the same lock. - this also holds for the SVGA_REG_ENABLE register write Hence it is safe to just remove that spinlock.

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.
