      target: Drop unnecessary CMD_T_DEV_ACTIVE check from transport_lun_remove_cmd · 0b66818a
      Nicholas Bellinger 提交于
      This patch drops an unnecessary acquire/release of se_cmd->t_state_lock within
      transport_lun_remove_cmd() when checking CMD_T_DEV_ACTIVE for invoking
      target_remove_from_state_list().
      
      For all fast path completion cases, transport_lun_remove_cmd() is always
      called ahead of transport_cmd_check_stop(), and since transport_cmd_check_stop()
      is calling target_remove_from_state_list() when remove_from_lists=true,
      the t_state_lock usage in transport_lun_remove_cmd() can safely be removed.

      target: Add transport_cmd_check_stop write_pending bit · 862e6389
      Nicholas Bellinger 提交于
      This patch adds a new transport_cmd_check_stop() parameter for signaling
      when TRANSPORT_WRITE_PENDING needs to be set.
      
      This allows transport_generic_new_cmd() to avoid the extra lock acquire/release
      of ->t_state_lock in the fast path for DMA_TO_DEVICE operations ahead of
      transport_cmd_check_stop() + se_tfo->write_pending().
