/*
 * DF-4403: no local trigger — the leaks fire on kmalloc(M_NOWAIT)/dmamap_load
 * failure inside the driver under kernel memory pressure, on a host with the
 * 3ware controller. Reproduction: run a memory bomb to near-exhaust the kernel
 * heap, then generate AENs (reseat a drive) and CAM I/O; observe:
 *   - AEN delivery stops permanently after one failed sector alloc
 *     (reqs[1] stuck BUSY: tws_get_request returns NULL forever, tws.c:763);
 *   - a CAM transaction hangs forever with its slot off every queue after a
 *     bus_dmamap_load failure in tws_execute_scsi (tws_cam.c:809).
