The process which handles\ncommands flush may see this command as needed to be flushed if the other\nprocess released its refcount but didn't release the index yet. Fix it\nby adding the needed spin lock.\n\nIt fixes the following warning trace:\n\nrefcount_t: addition on 0; use-after-free.\nWARNING: CPU: 11 PID: 540311 at lib/refcount.c:25 refcount_warn_saturate+0x80/0xe0\n...\nRIP: 0010:refcount_warn_saturate+0x80/0xe0\n...\nCall Trace:\n <TASK>\n mlx5_cmd_trigger_completions+0x293/0x340 [mlx5_core]\n mlx5_cmd_flush+0x3a/0xf0 [mlx5_core]\n enter_error_state+0x44/0x80 [mlx5_core]\n mlx5_fw_fatal_reporter_err_work+0x37/0xe0 [mlx5_core]\n process_one_work+0x1be/0x390\n worker_thread+0x4d/0x3d0\n ? rescuer_thread+0x350/0x350\n kthread+0x141/0x160\n ? set_kthread_struct+0x40/0x40\n ret_from_fork+0x1f/0x30\n </TASK>"
