simple-lock. The reviewer raises the following caveat: "I believe these changes open a non-critical race condition when adding memory to the pool for the zone. I think what will happen is that you could have two threads that are simultaneously adding additional memory when the pool runs out. This appears to not be a problem, however, since the re-aquisition of the lock will protect the list pointers." The submitter agrees that the race is non-critical, and points out that it already existed for the non-SMP case. He suggests that perhaps a sleep lock (using the lock manager) should be used to close that race. This might be worth revisiting after 3.0 is released.
