Two patches both in drivers. The iscsi one is fixing the cpumask issue
you commented on and the ufs one is a late arriving fix for conditions
that can occur in Host Performance Booster reads.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Daejun Park (1):
scsi: ufs: core: Fix referencing invalid rsp field
Mingzhe Zou (1):
scsi: target: Fix incorrect use of cpumask_t

Four fixes, all in drivers. These patches mosly fix error legs and
exceptional conditions (scsi_dh_alua, qla2xxx). The lpfc fixes are for
coding issues with lpfc features.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Brian Bunker (1):
scsi: scsi_dh_alua: Properly handle the ALUA transitioning state
Gleb Chesnokov (1):
scsi: qla2xxx: Fix missed DMA unmap for aborted commands
James Smart (2):
scsi: lpfc: Correct BDE DMA address assignment for GEN_REQ_WQE
scsi: lpfc: Fix split code for FLOGI on FCoE
