Hello,

I'm trying to make a VBOXHDDBACKEND (a memory-backed disk) by way of an
exercise. I have a few questions about some of the functions :

    /* pfnGetFileSize */
return 0 in case of no file backend ?

    /* pfnGetPCHSGeometry */
iscsihddbackend silently ignores this function call, not even setting the
pointer correctly ... is this a bug ?

    /* pfnSetPCHSGeometry */
again iscsihddbackend silently ignores this, is this correct behavior ?

    /* pfnGetLCHSGeometry */
again : silently ignored by iscsi ? is this correct behavior ?

    /* pfnSetLCHSGeometry */
again : silently ignored by iscsi ? is this correct behavior ?

Thanks,

Christophe
