Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull target updates from Nicholas Bellinger:
"There have been lots of work in a number of areas this past round.
The highlights include:
- Break out target_core_cdb.c emulation into SPC/SBC ops (hch)
- Add a parse_cdb method to target backend drivers (hch)
- Move sync_cache + write_same + unmap into spc_ops (hch)
- Use target_execute_cmd for WRITEs in iscsi_target + srpt (hch)
- Offload WRITE I/O backend submission in tcm_qla2xxx + tcm_fc (hch +
nab)
- Refactor core_update_device_list_for_node() into enable/disable
funcs (agrover)
- Replace the TCM processing thread with a TMR work queue (hch)
- Fix regression in transport_add_device_to_core_hba from TMR
conversion (DanC)
- Remove racy, now-redundant check of sess_tearing_down with qla2xxx
(roland)
- Add range checking, fix reading of data len + possible underflow in
UNMAP (roland)
- Allow for target_submit_cmd() returning errors + convert fabrics
(roland + nab)
- Drop bogus struct file usage for iSCSI/SCTP (viro)"
