[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.
