From c8e31f26feeb03dc6f51bff68135cc58431e099b Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Thu, 19 Jan 2012 13:39:17 -0800 Subject: target: Add SCF_SCSI_TMR_CDB usage and drop se_tmr_req_cache Change the test for if a cmd is a tmr request to checking if SCF_SCSI_TMR_CDB (a new flag) is set in cmd->se_cmd_flags. Also remove se_tmr_req_cache usage in favor of kzalloc usage, and make core_tmr_alloc_req() return int + setup se_cmd->se_tmr_req directly and fix up various fabric module usages Cc: Andy Grover Signed-off-by: Nicholas Bellinger --- include/target/target_core_base.h | 39 +++++++++++++++++++------------------ include/target/target_core_fabric.h | 2 +- 2 files changed, 21 insertions(+), 20 deletions(-) (limited to 'include/target') diff --git a/include/target/target_core_base.h b/include/target/target_core_base.h index 41dd91b98907..9d514e06625f 100644 --- a/include/target/target_core_base.h +++ b/include/target/target_core_base.h @@ -169,7 +169,8 @@ enum se_cmd_flags_table { SCF_EMULATED_TASK_SENSE = 0x00000004, SCF_SCSI_DATA_SG_IO_CDB = 0x00000008, SCF_SCSI_CONTROL_SG_IO_CDB = 0x00000010, - SCF_SCSI_NON_DATA_CDB = 0x00000040, + SCF_SCSI_NON_DATA_CDB = 0x00000020, + SCF_SCSI_TMR_CDB = 0x00000040, SCF_SCSI_CDB_EXCEPTION = 0x00000080, SCF_SCSI_RESERVATION_CONFLICT = 0x00000100, SCF_FUA = 0x00000200, @@ -498,6 +499,24 @@ struct se_task { struct completion task_stop_comp; }; +struct se_tmr_req { + /* Task Management function to be performed */ + u8 function; + /* Task Management response to send */ + u8 response; + int call_transport; + /* Reference to ITT that Task Mgmt should be performed */ + u32 ref_task_tag; + /* 64-bit encoded SAM LUN from $FABRIC_MOD TMR header */ + u64 ref_task_lun; + void *fabric_tmr_ptr; + struct se_cmd *task_cmd; + struct se_cmd *ref_cmd; + struct se_device *tmr_dev; + struct se_lun *tmr_lun; + struct list_head tmr_list; +}; + struct se_cmd { /* SAM response code being sent to initiator */ u8 scsi_status; @@ -586,24 +605,6 @@ struct se_cmd { }; -struct se_tmr_req { - /* Task Management function to be performed */ - u8 function; - /* Task Management response to send */ - u8 response; - int call_transport; - /* Reference to ITT that Task Mgmt should be performed */ - u32 ref_task_tag; - /* 64-bit encoded SAM LUN from $FABRIC_MOD TMR header */ - u64 ref_task_lun; - void *fabric_tmr_ptr; - struct se_cmd *task_cmd; - struct se_cmd *ref_cmd; - struct se_device *tmr_dev; - struct se_lun *tmr_lun; - struct list_head tmr_list; -}; - struct se_ua { u8 ua_asc; u8 ua_ascq; diff --git a/include/target/target_core_fabric.h b/include/target/target_core_fabric.h index d36fad317e78..c5c16efe396d 100644 --- a/include/target/target_core_fabric.h +++ b/include/target/target_core_fabric.h @@ -139,7 +139,7 @@ void target_wait_for_sess_cmds(struct se_session *, int); int core_alua_check_nonop_delay(struct se_cmd *); -struct se_tmr_req *core_tmr_alloc_req(struct se_cmd *, void *, u8, gfp_t); +int core_tmr_alloc_req(struct se_cmd *, void *, u8, gfp_t); void core_tmr_release_req(struct se_tmr_req *); int transport_generic_handle_tmr(struct se_cmd *); int transport_lookup_tmr_lun(struct se_cmd *, u32); -- cgit v1.2.3
