If a bo is created via xe_managed_bo_create_pin_map() then it cannot be freed by the driver using xe_bo_unpin_map_no_vm(), or indeed any other existing function. The DRM layer will still have a pointer stashed away for later freeing, causing a invalid memory access on driver unload. So add a helper for releasing the DRM action as well. v2: Drop 'xe' parameter (review feedbak from Michal W) Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: https://lore.kernel.org/r/20250910210237.603576-4-John.C.Harrison@Intel.com
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 reStructuredText 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.
