    ib_srpt: Convert acl lookup to modern get_initiator_node_acl usage · f246c941
    Nicholas Bellinger authored
    This patch does a simple conversion of ib_srpt code to use
    proper modern core_tpg_get_initiator_node_acl() lookup using
    se_node_acl->acl_kref, and drops the legacy internal list
    usage from srpt_lookup_acl().
    
    This involves doing transport_init_session() earlier, and
    making sure transport_free_session() is called during
    a se_node_acl lookup failure to drop the last ->acl_kref.
    
    Also, it adds a minor backwards-compat hack to avoid the
    potential for user-space wrt node-acl WWPN formatting by
    simply stripping off '0x' prefix from ch->sess_name, and
    retrying once if core_tpg_get_initiator_node_acl() fails.
    
    Finally, go ahead and drop port_acl_list port_acl_lock
    since they are no longer used.
