That patch causes the ib_srpt driver to crash as soon as the first SCSI command is received: kernel BUG at drivers/infiniband/ulp/srpt/ib_srpt.c:1439! invalid opcode: 0000 [#1] SMP Workqueue: target_completion target_complete_ok_work [target_core_mod] RIP: srpt_queue_response+0x437/0x4a0 [ib_srpt] Call Trace: srpt_queue_data_in+0x9/0x10 [ib_srpt] target_complete_ok_work+0x152/0x2b0 [target_core_mod] process_one_work+0x197/0x480 worker_thread+0x49/0x490 kthread+0xea/0x100 ret_from_fork+0x22/0x40 Aside from the crash, the shortcomings of that patch are as follows: - It makes the ib_srpt driver use I/O contexts allocated by transport_alloc_session_tags() but it does not initialize these I/O contexts properly. All the initializations performed by srpt_alloc_ioctx() are skipped. - It swaps the order of the send ioctx allocation and the transition to RTR mode which is wrong. - The amount of memory that is needed for I/O contexts is doubled. - srpt_rdma_ch.free_list is no longer used but is not removed.
