    Subject[PATCH v3] xen block backend.
    The following patch implements the Xen block backend driver for
    upstream Linux. This is the host side counterpart to the frontend driver
    in drivers/block/xen-blkfront.c. The PV protocol is also implemented by
    frontend drivers in other OSes too, such as the BSDs and even Windows.

    This driver has a long history as an out of tree driver but I am
    submitting it here as a single monolithic patch to aid review. Once it
    has been reviewed and is considered suitable for merging can we perhaps
    consider merging the equivalent git branch which maintains much of

    The patch is based on the driver from the xen.git pvops kernel tree but
    has been put through the wringer plus several manual
    cleanup passes. It has also been moved from drivers/xen/blkback to

    The git tree of the broken out driver is available at:

    git:// devel/xen-blkback-v3

    Note that this driver depends on couple of fixes to the Xen backend
    subsystem. Those are available in devel/backend.base.v3 branch and are
    intended for the 2.6.40 merge window.
