From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> Hi folks, This series is a WIP for adding se_session->sess_kref into target core to address a long standing set of issues wrt to active session shutdown and explict NodeACL group configuration. This includes changing iscsi-target to co-exist with internal reference counting, and converting qla2xxx internal qla_tgt_sess->sess_kref to use se_session->sess_kref for all cases. It also re-factors qla_tgt_sess shutdown -> release code to run outside of qla_hw_data->hardware_lock + interrupt execution using system_wq process context. So far the changes have been tested with normal session creation/deletion for iscsi-target, loopback, tcm_fc(fcoe) and qla2xxx WWPNs, but need more testing with active I/O shutdown. Please have a look.. Thanks, --nab Nicholas Bellinger (5): target: Add se_sess->sess_kref + get/put helpers target: Add se_node_acl->acl_free_comp for NodeACL release path target: Make dynamic NodeACL shutdown clear comp_nacl bit iscsi-target: Convert to use target_put_session + sess_kref qla_target/tcm_qla2xxx: Convert to use target_put_session + sess_kref drivers/scsi/qla2xxx/qla_target.c | 121 +++++++++----------------- drivers/scsi/qla2xxx/qla_target.h | 9 +- drivers/scsi/qla2xxx/tcm_qla2xxx.c | 71 +++++++-------- drivers/target/iscsi/iscsi_target.c | 6 +- drivers/target/iscsi/iscsi_target_configfs.c | 6 +- drivers/target/iscsi/iscsi_target_login.c | 6 +- drivers/target/target_core_tpg.c | 23 +++--- drivers/target/target_core_transport.c | 62 ++++++++++---- include/target/target_core_base.h | 2 + include/target/target_core_fabric.h | 2 + 10 files changed, 152 insertions(+), 156 deletions(-) -- 1.7.2.5 -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
