Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull scsi-target changes from Nicholas Bellinger: "There has been lots of work in existing code in a number of areas this past cycle. The major highlights have been: * Removal of transport_do_task_sg_chain() from core + fabrics (Roland) * target-core: Removal of se_task abstraction from target-core and enforce hw_max_sectors for pSCSI backends (hch) * Re-factoring of iscsi-target tx immediate/response queues (agrover) * Conversion of iscsi-target back to using target core memory allocation logic (agrover) We've had one last minute iscsi-target patch go into for-next to address a nasty regression bug related to the target core allocation logic conversion from agrover that is not included in friday's linux-next build, but has been included in this series. On the new fabric module code front for-3.5, here is a brief status update for the three currently in flight this round: * usb-gadget target driver: Sebastian Siewior's driver for supporting usb-gadget target mode operation. This will be going out as a separate PULL request from target-pending/usb-target-merge with subsystem maintainer ACKs. There is one minor target-core patch in this series required to function. * sbp ieee-1394/firewire target driver: Chris Boot's driver for supportting the Serial Block Protocol (SBP) across IEEE-1394 Firewire hardware. This will be going out as a separate PULL request from target-pending/sbp-target-merge with two additional drivers/firewire/ patches w/ subsystem maintainer ACKs. * qla2xxx LLD target mode infrastructure changes + tcm_qla2xxx: The Qlogic >= 24xx series HW target mode LLD infrastructure patch-set and tcm_qla2xxx fabric driver. Support for FC target mode using qla2xxx LLD code has been officially submitted by Qlogic to James below, and is currently outstanding but not yet merged into scsi.git/for-next.. [PATCH 00/22] qla2xxx: Updates for scsi "misc" branch http://www.spinics.net/lists/linux-scsi/msg59350.html Note there are *zero* direct dependencies upon this for-next series for the qla2xxx LLD target + tcm_qla2xxx patches submitted above, and over the last days the target mode team has been tracking down an tcm_qla2xxx specific active I/O shutdown bug that appears to now be almost squashed for 3.5-rc-fixes." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (47 commits) iscsi-target: Fix iov_count calculation bug in iscsit_allocate_iovecs iscsi-target: remove dead code in iscsi_check_valuelist_for_support target: Handle ATA_16 passthrough for pSCSI backend devices target: Add MI_REPORT_TARGET_PGS ext. header + implict_trans_secs attribute target: Fix MAINTENANCE_IN service action CDB checks to use lower 5 bits target: add support for the WRITE_VERIFY command target: make target_put_session void target: cleanup transport_execute_tasks() target: Remove max_sectors device attribute for modern se_task less code target: lock => unlock typo in transport_lun_wait_for_tasks target: Enforce hw_max_sectors for SCF_SCSI_DATA_SG_IO_CDB target: remove the t_se_count field in struct se_cmd target: remove the t_task_cdbs_ex_left field in struct se_cmd target: remove the t_task_cdbs_left field in struct se_cmd target: remove struct se_task target: move the state and execute lists to the command target: simplify command to task linkage target: always allocate a single task target: replace ->execute_task with ->execute_cmd target: remove the task_sectors field in struct se_task ...
