The next biggest impact is the target fix for wrong credentials used to load a module because it's affecting new kernels installed on selinux based distributions. The other three fixes are an obvious off by one and SATA protocol issues. The patch is available here: git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes The short changelog is: Alexander Wetzel (1): scsi: sg: Avoid race in error handling & drop bogus warn Dan Carpenter (1): scsi: qla2xxx: Fix off by one in qla_edif_app_getstats() Maurizio Lombardi (1): scsi: target: Fix SELinux error when systemd-modules loads the target module Xiang Chen (2): scsi: hisi_sas: Modify the deadline for ata_wait_after_reset() scsi: hisi_sas: Handle the NCQ error returned by D2H frame And the diffstat: drivers/scsi/hisi_sas/hisi_sas_main.c | 2 +- drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 10 +++++++++- drivers/scsi/qla2xxx/qla_edif.c | 2 +- drivers/scsi/sg.c | 18 ++++++++++-------- drivers/target/target_core_configfs.c | 12 ++++++++++++ 5 files changed, 33 insertions(+), 11 deletions(-) With full diff below.
