    qla2xxx: Check + fail when npiv_vports_inuse exists in shutdown · 3c231bda
    Nicholas Bellinger authored
    This patch adds an check to qlt_stop_phase1() to avoid shutdown
    when the base_vha contains a non-zero fc_host->npiv_vports_inuse
    count.
    
    This includes holding qla_tgt_mutex in qlt_stop_phase1() between
    the fc_host->npiv_vports_inuse check + setting of tgt->tgt_stop to
    avoid a possible race between qlt_lport_register() -> tcm_qla2xxx
    -> tcm_qla2xxx_lport_register_npiv_cb() calling fc_vport_create().
