Patch 1 ensures proper allocation checks before using pointers in rocket_job_open() 2. Patch 2 fixes an unreachable memory leak of the scheduler array when running on single-core setups (e.g., num_cores == 1), where drm_sched_entity_init() drops the array pointer. Link to v5: https://lore.kernel.org/all/20260818041505.1579320-1-triet.hoang.dev@gmail.com/ Changes in v6: - Rebase on top of drm-misc-next (base commit 5052ea2e6bfc43c64b851c596d3675d17e05e631) - Addressed review feedback from previous iterations. - Added Fixes and Tested-by tags where applicable.
