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@xxxxxxxxxx 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:
