Subject: [GIT PULL] target for-next v3.5-rc1 updates + new drivers merge
status
Hi Linus & Co,
With the v3.5 merge window now officially upon us, here is the first
pull request for the current set of target pending for-next core +
existing fabric module changes for the v3.5 round..
Please go ahead and pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next
Thank you to everyone who has contributed this round.
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.
Please let us know if you have any concerns,
Thanks!
