Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
"This contains the usual set of updates and bugfixes to target-core +
existing fabric module code, along with a handful of the patches
destined for v3.3 stable.
It also contains the necessary target-core infrastructure pieces
required to run using tcm_qla2xxx.ko WWPNs with the new Qlogic Fibre
Channel fabric module currently queued in target-pending/for-next-merge,
and coming for round 2.
The highlights for this series include:
- Add target_submit_tmr() helper function for fabric task management
(andy)
- Convert tcm_fc to use target_submit_tmr() (andy)
- Replace target core various cmd flags with a transport state (hch)
- Convert loopback to use workqueue submission (hch)
- Convert target core to use array_zalloc for tpg_lun_list (joern)
- Convert target core to use array_zalloc for device_list (joern)
- Add target core support for TMR_ABORT_TASK (nab)
- Add target core se_sess->sess_kref + get/put helpers (nab)
- Add target core se_node_acl->acl_kref for ->acl_free_comp usage
(nab)
- Convert iscsi-target to use target_put_session + sess_kref (nab)
- Fix tcm_fc fc_exch memory leak in ft_send_resp_status (nab)
- Fix ib_srpt srpt_handle_cmd send_ioctx->ioctx_kref leak on
exception (nab)
- Fix target core up handling of short INQUIRY buffers (roland)
- Untangle target-core front-end and back-end meanings of max_sectors
attribute (roland)
- Set loopback residual field for SCSI commands (roland)
- Fix target-core 16-bit target ports for SET TARGET PORT GROUPS
emulation (roland)
Thanks again to Andy, Christoph, Joern, Roland, and everyone who has
contributed this round!"
