[PATCH 0/2] Fit one IB struct amdgpu_job into a 512 byte slab

[Tvrtko Ursulin]

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.

  drm/amdgpu: Remove hole from struct amdgpu_ib
  drm/amdgpu: Reduce holes in struct amdgpu_job
