qib_chg_pioavailkernel - change which send buffers are available for kernel : the qlogic_ib device : the starting send buffer number : the number of send buffers : true if the buffers are available for kernel use, false otherwise

qib_disarm_piobufs - cancel a range of PIO buffers : the qlogic_ib device : the first PIO buffer to cancel : the number of PIO buffers to cancel

Cancel a range of PIO buffers. Used at user process close, in case it died while writing to a PIO buffer.
