In case of LAP are used for RoCE, it can lead to a problem of sleeping a context while spin lock is held in below flow. cm_lap_handler ->spin_lock -> <..switch_case..> -> cm_init_av_for_response -> ib_init_ah_from_wc -> rdma_addr_find_l2_eth_by_grh wait_for_completion() Therefore ah attribute initialization is done for incoming lap requests outside of the lock context.
