      iscsi-target; Allow an extra tag_num / 2 number of percpu_ida tags · 9e20ae33
      Nicholas Bellinger 提交于
      This patch bumps the default number of tags allocated per session by
      iscsi-target via transport_alloc_session_tags() -> percpu_ida_init()
      by another (tag_num / 2).
      
      This is done to take into account the tags waiting to be acknowledged
      and released in iscsit_ack_from_expstatsn(), but who's number are not
      directly limited by the CmdSN Window queue_depth being enforced by
      the target.
      
      Using a larger value here is also useful to prevent percpu_ida_alloc()
      from having to steal tags from other CPUs when no tags are available
      on the local CPU, while waiting for unacknowledged tags to be released.

      iscsi-target: Perform release of acknowledged tags from RX context · f56cbbb4
      Nicholas Bellinger 提交于
      This patch converts iscsit_ack_from_expstatsn() to populate a local
      ack_list of commands, and call iscsit_free_cmd() directly from RX
      thread context, instead of using iscsit_add_cmd_to_immediate_queue()
      to queue the acknowledged commands to be released from TX thread
      context.
      
      It is helpful to release the acknowledge commands as quickly as
      possible, along with the associated percpu_ida tags, in order to
      prevent percpu_ida_alloc() from having to steal tags from other
      CPUs while waiting for iscsit_free_cmd() to happen from TX thread
      context.

      iscsi-target: Only perform wait_for_tasks when performing shutdown · e255a285
      Nicholas Bellinger 提交于
      This patch changes transport_generic_free_cmd() to only wait_for_tasks
      when shutdown=true is passed to iscsit_free_cmd().
      
      With the advent of >= v3.10 iscsi-target code using se_cmd->cmd_kref,
      the extra wait_for_tasks with shutdown=false is unnecessary, and may
      end up causing an extra context switch when releasing WRITEs.

      target: Fall back to vzalloc upon ->sess_cmd_map kzalloc failure · 8c7f6e9b
      Nicholas Bellinger 提交于
      This patch changes transport_alloc_session_tags() to fall back to
      use vzalloc when kzalloc fails for big tag_num that end up generating
      larger order allocations.
      
      Also use is_vmalloc_addr() in transport_alloc_session_tags() failure
      path, and normal transport_free_session() path to determine when
      vfree() needs to be called instead of kfree().

        - Use  __GFP_NOWARN | __GFP_REPEAT for sess_cmd_map kzalloc (mst)
