Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger: "The bulk of the changes are in qla2xxx target driver code to address various issues found during Cavium/QLogic's internal testing (stable CC's included), along with a few other stability and smaller miscellaneous improvements. There are also a couple of different patch sets from Mike Christie, which have been a result of his work to use target-core ALUA logic together with tcm-user backend driver. Finally, a patch to address some long standing issues with pass-through SCSI export of TYPE_TAPE + TYPE_MEDIUM_CHANGER devices, which will make folks using physical (or virtual) magnetic tape happy" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (28 commits) qla2xxx: Update driver version to 9.00.00.00-k qla2xxx: Fix delayed response to command for loop mode/direct connect. qla2xxx: Change scsi host lookup method. qla2xxx: Add DebugFS node to display Port Database qla2xxx: Use IOCB interface to submit non-critical MBX. qla2xxx: Add async new target notification qla2xxx: Export DIF stats via debugfs qla2xxx: Improve T10-DIF/PI handling in driver. qla2xxx: Allow relogin to proceed if remote login did not finish qla2xxx: Fix sess_lock & hardware_lock lock order problem. qla2xxx: Fix inadequate lock protection for ABTS. qla2xxx: Fix request queue corruption. qla2xxx: Fix memory leak for abts processing qla2xxx: Allow vref count to timeout on vport delete. tcmu: Convert cmd_time_out into backend device attribute tcmu: make cmd timeout configurable tcmu: add helper to check if dev was configured target: fix race during implicit transition work flushes target: allow userspace to set state to transitioning target: fix ALUA transition timeout handling ...
