This series of patches allows to connect real SCSI device to the virtual
SCSI controller of Qemu using the SCSI Generic interface (/dev/sg)

for instance:

qemu -hda my_disk.qcow2 -drive file=3D/dev/sg3,if=3Dscsi

[PATCH 1/3] SG support (Synchronous I/O)

    This patch allows to connect the virtual SCSI interface of Qemu=20
    to a real SCSI device of the host. it uses synchronous SCSI I/O.

[PATCH 2/3] SG support (Asynchronous Read/Write)

    This patch modifies scsi_read_data() and scsi_write_data() to use=20
    asynchronous I/O.=20

[PATCH 3/3] SG support (Asynchronous Send Command)

    This patch modifies scsi_send_command() to use asynchronous I/O .
