SCSI fixes for the 4.0+ merge window
Subsystems (3)
James Bottomley
maintainerI'd like to say these were a set of regressions for the recent merge window code. Unfortunately, they all predate the merge window code (stable cc'd). There's two fixes for data integrity (mostly only showing up on module removal), an mvsas crash with expander attached SATA devices which goes back to the dawn of the driver but is only just being picked up as sas expanders become a standard item in low end server hardware, an am53c974 one because the interrupt data isn't fully initialised before the line is and a megaraid_sas one because it uses smp_processor_id() to select MSI-X queues and that now triggers a WARN_ON().
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-misc
The Short Changelog is
Christoph Hellwig (1):
megaraid_sas: use raw_smp_processor_id()
Hannes Reinecke (1):
am53c974: Fix crash during modprobe
James Bottomley (1):
mvsas: fix panic on expander attached SATA devices
Martin K. Petersen (2):
sd: Fix missing ATO tag check
sd: Unregister integrity profile
