The array is shared by the adapter's connections\nand initialized with XA_FLAGS_LOCK_BH.  However, chcr_ktls_dev_del() and\nthe chcr_ktls_dev_add() error path use xa_erase(), which takes the XArray\nlock without disabling softirqs.\n\nWhen cleanup runs with softirqs enabled, a receive softirq for another\nconnection on the same CPU can interrupt the erase and spin on the lock\nheld by the interrupted task.  Use xa_erase_bh() at both sites to match\nthe insertion path."
