  1. “not much” I think there’s some parts where it doesn’t matter much – ttys, I think? It may be a question of impact over completeness.

  2. This change doesn’t make all of CAM MPSAFE (most of CAM already was); it removes the implicit MPLOCK around CAM I/O completions SWIs. This will only improve performance when CAM completions were contending on the MPLOCK with other non-MPSAFE subsystems.
