Julian Wiedmann 2223318c28 s390/qdio: remove 'merge_pending' mechanism ... For non-QEBSM devices, get_buf_states() merges PENDING and EMPTY buffers into a single group of finished buffers. To allow the upper-layer driver to differentiate between the two states, qdio_check_pending() looks at each buffer's state again and sets the sbal_state flag to QDIO_OUTBUF_STATE_FLAG_PENDING accordingly. So effectively we're spending overhead on _every_ Output Queue inspection, just to avoid some additional TX completion calls in case a group of buffers has completed with mixed EMPTY / PENDING state. Given that PENDING buffers should rarely occur, this is a bad trade-off. In particular so as the additional checks in get_buf_states() affect _all_ device types (even those that don't use the PENDING state). Rip it all out, and just report the PENDING completions separately as we already do for QEBSM devices.
