From: Nicholas Bellinger <nab@linux-iscsi.org>
Hi James and Co,
This series is resend of four patches that should be considered critical target core bugfixes for .39 that have been under stress testing in a couple of different labs recently using lio-core-2.6.git/lio-4.1 (.39-rcX) and /lio-4.0 (.38.3) branch code.
These are all important bugfixes that are required to run with in-flight .40 HW target drivers in the upstream LIO tree. This includes fixes for the main transport_do_task_sg_chain() Data I/O mapping logic, and task->task_sg[] shutdown path from MSI-X interrupt context. These bugfixes apply for all of the following HW fabric drivers:
tcm_fc(openfcoe) w/ ddp offload, tcm_qla2xxx, ib_srpt and ibmvscsis.
These patches address issues that are able to easily produce OOPsen with small backstore max_sectors values. Please review+apply for .39 and also queue into stable@kernel.org for .38.
The series is also available here for a direct pull:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/scsi-post-merge-2.6.git for-39-rc-fixes
and has been made against the following scsi-rc-fixes-2.6.git HEAD:

Thanks!
