4.10 and -stable fix for virtio_blk and virtually mapped stacks
Without this fix attempts to do scsi passthrough on virtio_blk will crash
the system on virtually mapped stacks, which is something happening during
boot with many distros.

make SCSI passthrough support optional
Hi all,
this series builds on my previous changes in Jens' for-4.11/rq-refactor
branch that split out the BLOCK_PC fields from struct request into a new
struct scsi_request, and makes support for struct scsi_request and the
SCSI passthrough ioctls optional. It is now only enabled by drivers that
need it.
In addition I've made SCSI passthrough support in the virtio_blk driver an

[PATCH] Staging: hv: storvsc: Show the modulename in /sys/class/scsi_host/*/proc_name
mkinitrd relies on /sys/class/scsi_host/*/proc_name instead of
/sys/block/sd*/device/../../../moalias to get the scsi driver module
name.
As a fallback the sysfs driver name could be used, which does not match
the module name either ('storvsc' vs. 'hv_storvsc').

[PATCH 00/22] Staging: hv: Cleanup storage drivers - Phase IV
More cleanup. In this patch-set we deal with the following issues:
1) While a Linux guest on Hyper-V can be assigned removable media
devices (DVD, floppy etc), these devices are not handled by the
Hyper-V block driver. So, we cleanup all the dead code
dealing with removable media devices.
2) There were multiple functions to retrieve information about
the device. Since much of
