Testing with Loopback I found that, after a Loopback LUN has executed a TMR, I can no longer unlink the LUN. The rm command hangs in transport_clear_lun_ref() at wait_for_completion(&lun->lun_shutdown_comp) The reason is, that transport_lun_remove_cmd() is not called at the end of target_tmr_work(). It seems, that in other fabrics this call happens implicitly when the fabric drivers call transport_generic_free_cmd() during their ->queue_tm_rsp(). Unfortunately Loopback seems to not comply to the common way of calling transport_generic_free_cmd() from ->queue_*(). Instead it calls transport_generic_free_cmd() from its ->check_stop_free() only. But the ->check_stop_free() is called by transport_cmd_check_stop_to_fabric() after it has reset the se_cmd->se_lun pointer. Therefore the following transport_generic_free_cmd() skips the transport_lun_remove_cmd(). So this patch re-adds the transport_lun_remove_cmd() at the end of target_tmr_work(), which was removed during commit |
