[SCSI] target: add initial statistics
This patch adds a target_core_mib.c statistics conversion for backend context struct se_subsystem_dev + struct se_device config_group based statistics in target_core_device.c using CONFIGFS_EATTR() based struct config_item_types from target_core_stat.c code. The conversion from backend /proc/scsi_target/mib/ context output to configfs default groups+attributes include scsi_dev, scsi_lu, and scsi_tgt_dev output from within individual: /sys/kernel/config/target/core/$HBA/DEV/ The legacy procfs output now appear as individual configfs attributes under: *) $HBA/$DEV/statistics/scsi_dev: |-- indx |-- inst |-- ports `-- role *) $HBA/$DEV/statistics/scsi_lu: |-- creation_time |-- dev |-- dev_type |-- full_stat |-- hs_num_cmds |-- indx |-- inst |-- lu_name |-- lun |-- num_cmds |-- prod |-- read_mbytes |-- resets |-- rev |-- state_bit |-- status |-- vend `-- write_mbytes *) $HBA/$DEV/statistics/scsi_tgt_dev: |-- indx |-- inst |-- non_access_lus |-- num_lus |-- resets `-- status The conversion from backend /proc/scsi_target/mib/ context output to configfs default groups+attributes include scsi_port, scsi_tgt_port and scsi_transport output from within individual: /sys/kernel/config/target/fabric/$WWN/tpgt_$TPGT/lun/lun_$LUN_ID/statistics/ The legacy procfs output now appear as individual configfs attributes under: *) fabric/$WWN/tpgt_$TPGT/lun/lun_$LUN_ID/statistics/scsi_port |-- busy_count |-- dev |-- indx |-- inst `-- role *) fabric/$WWN/tpgt_$TPGT/lun/lun_$LUN_ID/statistics/scsi_tgt_port |-- dev |-- hs_in_cmds |-- in_cmds |-- indx |-- inst |-- name |-- port_index |-- read_mbytes `-- write_mbytes *) fabric/$WWN/tpgt_$TPGT/lun/lun_$LUN_ID/statistics/scsi_transport |-- dev_name |-- device |-- indx `-- inst The conversion from backend /proc/scsi_target/mib/ context output to configfs default groups+attributes include scsi_att_intr_port and scsi_auth_intr output from within individual: /sys/kernel/config/target/fabric/$WWN/tpgt_$TPGT/acls/$INITIATOR_WWN/lun_$LUN_ID/statistics/ The legacy procfs output now appear as individual configfs attributes under: *) acls/$INITIATOR_WWN/lun_$LUN_ID/statistics/scsi_att_intr_port |-- dev |-- indx |-- inst |-- port |-- port_auth_indx `-- port_ident *) acls/$INITIATOR_WWN/lun_$LUN_ID/statistics/scsi_auth_intr |-- att_count |-- creation_time |-- dev |-- dev_or_port |-- hs_num_cmds |-- indx |-- inst |-- intr_name |-- map_indx |-- num_cmds |-- port |-- read_mbytes |-- row_status `-- write_mbytes Also, this includes adding struct target_fabric_configfs_template-> tfc_wwn_fabric_stats_cit and ->tfc_tpg_nacl_stat_cit respectively for use during target_core_fabric_configfs.c:target_fabric_setup_cits() Signed-off-by: Nicholas A.
