Revert "drm: Add directive to format code in comment"

2025-09-13T09:17:34Z

Commit 6cc44e9618f03f ("drm: Add directive to format code in comment") fixes original Sphinx indentation warning as introduced in 471920ce25d50b ("drm/gpuvm: Add locking helpers"), by means of using code-block:: directive. It semantically conflicts with earlier bb324f85f72284 ("drm/gpuvm: Wrap drm_gpuvm_sm_map_exec_lock() expected usage in literal code block") that did the same using double colon syntax instead. These duplicated literal code block directives causes the original warnings not being fixed. Revert 6cc44e9618f03f to keep things rolling without these warnings.

drm/gpuvm: Add locking helpers

2025-07-04T18:09:43Z

For UNMAP/REMAP steps we could be needing to lock objects that are not explicitly listed in the VM_BIND ioctl in order to tear-down unmapped VAs. These helpers handle locking/preparing the needed objects. Note that these functions do not strictly require the VM changes to be applied before the next drm_gpuvm_sm_map_lock()/_unmap_lock() call. In the case that VM changes from an earlier drm_gpuvm_sm_map()/_unmap() call result in a differing sequence of steps when the VM changes are actually applied, it will be the same set of GEM objects involved, so the locking is still correct. v2: Rename to drm_gpuvm_sm_*_exec_locked() [Danilo] v3: Expand comments to show expected usage, and explain how the usage is safe in the case of overlapping driver VM_BIND ops.
