A lot of the workloads create jobs with just one IB and if we re-order some struct members we can stop that allocation spilling into the 1k SLAB bucket. Before: sizeof(struct amdgpu_job) + sizeof(struct amdgpu_ib) = 480 + 40 = 520 After: sizeof(struct amdgpu_job) + sizeof(struct amdgpu_ib) = 472 + 32 = 504 It is not a huge gain in the big picture but every little helps.
