+Subject: block: add and use scsi_blk_cmd_ioctl
+
+From: Paolo Bonzini <pbonzini@redhat.com>
+
+commit 577ebb374c78314ac4617242f509e2f5e7156649 upstream.
+
+Introduce a wrapper around scsi_cmd_ioctl that takes a block device.
+
+The function will then be enhanced to detect partition block devices
+and, in that case, subject the ioctls to whitelisting.
